Edwin Hubble, “A Relation Between Distance and Radial Velocity Among Extra-Galactic Nebulae,” Proceedings of the National Academy of Sciences, 1929.
Common objections
- ObjectionHubble himself never accepted that expansion implied a beginning, and expansion is compatible with steady-state models that were taken seriously until the 1960s.
- Response
Both true. Expansion alone did not settle the question; the steady-state model was a live alternative until the microwave background killed it, and Hubble stayed agnostic. Hubble’s measurement is cited as the observational turning point: the first evidence that the universe is not static, which is what everyone from Aristotle to Einstein had assumed. The next exhibit, the cosmic microwave background, is what made a hot, dense beginning the mainstream view.
- ObjectionEven if the universe began, why must a beginning have a cause? Time itself began; there was no “before” in which a cause could act. Causation is a concept inside the universe.
- Response
This is the strongest philosophical reply to the argument from a beginning. The theistic response is that a cause of the beginning of time need not be earlier in time, only prior in the order of dependence, the way (on some views) a cause can be simultaneous with its effect. Whether that is coherent is a live debate among philosophers of time. This claim deliberately stops short: it says the universe had a beginning and does not, by itself, say who or what caused it. The further step is argued in the Atheism case, where this objection is met head on.

Common objections
- ObjectionThe CMB is the afterglow of the universe becoming transparent about 380,000 years after the Big Bang. It tells us nothing about t = 0 or whether there was anything before.
- Response
Correct. The microwave background confirms a hot, dense early state and rules out steady-state models; it does not reach the beginning itself. Start here means the start of the current expansion phase. The stronger claim about an absolute beginning rests on the singularity theorems and on the Borde-Guth-Vilenkin theorem, which the Atheism case cites, and even those leave the quantum-gravity regime open. What the CMB settles is that the universe has a history and a finite age, which is what the older eternal-universe picture denied.
- ObjectionThe Big Bang is the beginning of the current expansion, not necessarily of everything. Inflation, bounce models, and quantum gravity approaches all allow a past before it. Isn’t “the universe had a beginning” just one reading?
- Response
That is accurate and worth saying plainly. The standard model traces the observable universe back to a hot, dense state about 13.8 billion years ago; what happened at or before the Planck time is not known, and several models extend the past. What can be said with confidence is that the observable universe has a finite age and that eternal-past models face the Borde-Guth-Vilenkin theorem’s constraint on average expansion. The careful version of the claim is that the observable universe has a finite past and that models with an infinite past face serious theoretical obstacles, not that physics has closed the question.
Claim 02
The idea that science and religion have always been at war was popularized by two writers in the late 1800s and has since been set aside by most historians of science.

Common objections
- ObjectionDraper’s target was the Catholic Church’s reaction to modern science after 1870, Vatican I and the Syllabus of Errors. He was responding to real events, not inventing a conflict from nothing.
- Response
Fair. Draper wrote in the context of genuine nineteenth-century tensions, and his anti-Catholic polemic had contemporary causes. The historians’ criticism is not that he invented conflict but that he projected it backward onto the whole of history and got much of the history wrong, the flat-earth myth included. Draper generalized from real contemporary conflicts to a false universal thesis, and it is the universal thesis that historians have set aside.

Common objections
- ObjectionWhite’s title says warfare of science with theology, not religion. He was explicitly defending religion against dogmatic theology. Isn’t his aim being misrepresented?
- Response
Correct, and the title should be read as written. White’s distinction between religion (good) and dogmatic theology (the enemy of science) is a real feature of the book. It does not rescue his history, which is where several of the enduring myths come from: Columbus and the flat earth, the Church forbidding dissection. The historians’ verdict on White’s reliability stands regardless of his stated aim, and it is his history, not his aim, that the conflict thesis rests on.

Common objections
- ObjectionRonald Numbers is also the leading historian of American creationism, and his work documents a very real, ongoing conflict between a large segment of Christianity and evolutionary biology. Isn’t citing him for “no war” selective?
- Response
Numbers’s The Creationists documents exactly that conflict, and it is the honest complement to Galileo Goes to Jail. His position is that the always at war thesis is false and that particular conflicts, including the one over evolution, are real and have specific causes. Historians call this the complexity thesis: the relationship has included conflict, cooperation, and indifference depending on time and place. Some contemporary Christian communities are in real conflict with mainstream science, which is a fact about those communities rather than about Christianity’s relationship to science as such. Both halves belong in the picture.
Claim 03
A Catholic priest was among the first to derive an expanding-universe model, and the first to propose it had a beginning, while refusing to treat it as proof of God.
The Big Bang is sometimes used as if it were an argument against religion. The history runs the other way. The Russian mathematician Alexander Friedmann first derived expanding-universe solutions to Einstein’s equations in 1922. Georges Lemaitre, a trained physicist and an ordained Catholic priest, independently derived the same kind of solution in 1927, connected it to real astronomical observation, and in 1931 was the first to propose that the universe began from a single primeval state. Just as telling, he insisted that his science not be used as religious proof, which cuts against the idea that believers only reach conclusions that flatter their faith.

Common objections
- ObjectionThe primeval atom was speculative and in some respects wrong. The modern Big Bang model owes as much to Gamow, Alpher, and Herman. Doesn’t calling Lemaitre the father of the Big Bang overstate his role?
- Response
The 1931 proposal was qualitative, and later work by Gamow and his colleagues gave it physical content, including the prediction of the microwave background. Lemaitre remains the first to propose that the universe began from a single primeval state and to connect the expansion law to observation, which is what is claimed here. The father title is conventional; a founder is safer, and nothing in the claim depends on which word you use.

Common objections
- ObjectionThe story that Lemaitre persuaded the Pope to stop is partly legend. The evidence for a direct intervention is thin, and the Pope’s later speeches simply avoided the topic.
- Response
Historians such as Dominique Lambert have shown that Lemaitre did express his discomfort through Church channels, and that the Pope’s subsequent silence is consistent with having heard it, but a dramatic personal confrontation is not documented. Lemaitre expressed his concern is the accurate phrasing; worked to persuade the Pope claims more than the record supports. The substance, that the scientist who proposed the beginning did not want it used as a proof of God, is well attested in his own words.
- ObjectionLemaitre’s own insistence that his science not be used as religious proof is an argument against this entire case, which uses the Big Bang exactly that way.
- Response
Lemaitre’s caution deserves to be taken seriously. He distinguished between physics, which describes the natural beginning, and the doctrine of creation, which concerns the world’s dependence on God and is compatible with any physics. The Big Bang is not used here as proof of God. It is used as a fact that fits theism and disconfirms one older form of naturalism, the eternal universe, which is a modest use Lemaitre might well have accepted. The line he drew is the line this case tries to stay on the right side of.

Common objections
- ObjectionGalileo stayed Catholic because leaving the Church in 1630s Italy wasn’t an option. His private letters show real bitterness. What does personal piety under house arrest tell us about whether science and faith are compatible?
- Response
The point about social constraint is fair; nobody can read Galileo’s heart under house arrest. What is documented is that his scientific work and his faith coexisted in his own writings before the trial. The Letter to the Grand Duchess Christina argues, as a believer, for interpreting Scripture in light of demonstrated science, and he saw the conflict as being with particular churchmen rather than with Christianity. He is cited for that, not for his sincerity under duress.

Common objections
- ObjectionWhatever the politics, the Church declared heliocentrism formally heretical, banned Copernicus’s book, and forced a seventy-year-old man to recant a true theory under threat. Does complicating the story change the verdict?
- Response
No, and the verdict should be said first: Galileo’s treatment was unjust, and the Church was wrong. The narrow point of this claim is that the affair does not fit the template of religion versus science as a general model. The Church had astronomers who accepted Galileo’s observations, his opponents included secular Aristotelians, and the specific issue was who had authority to interpret Scripture in light of not-yet-proven science. It was an authority dispute in which the Church was wrong. Both halves belong on the record, and neither cancels the other.

Common objections
- ObjectionThe cosmological constant turned out to be real. Dark energy, discovered in 1998, is exactly that term. Einstein’s blunder was one of the great correct guesses in physics. Hasn’t this anecdote aged badly?
- Response
That is the first thing any physicist will say, and it is right. The constant was reintroduced for a different reason (accelerating expansion) and with a different value, so the story is nuanced: Einstein was wrong to use the term to force a static universe and right, by accident, that it belongs in the equations. The point of this claim survives the update. The assumption of an eternal, static universe was so strong that even Einstein bent his theory to it, and the evidence bent it back.

Common objections
- ObjectionIf the quote may be apocryphal, why include it at all? Using a possibly invented quote, even with caveats, is a bad look on a site about accuracy.
- Response
It is included precisely to correct the common apologetics practice of quoting it as certain, and the scholarly investigation into its origin is cited. That is the right way to handle a famous but uncertain quotation: report it, cite the study, and rest the point on what is documented, which is Einstein’s own published abandonment of the constant. Treat the quote as a footnote to the documented history, not as the headline.
Claim 06

Sources
John Hedley Brooke, “Science and Religion: Some Historical Perspectives” (Cambridge University Press, 1991)
Common objections
- ObjectionNearly everyone in seventeenth-century Europe was a Christian. That the founders of science were too is a fact about the population, not about any link between faith and science.
- Response
This is the strongest objection and it deserves a direct answer. Two replies. Several of the founders (Kepler, Boyle, Newton) said in their own words that their theology motivated their science, which is more than demographic coincidence. And the stronger thesis, that Christianity caused modern science, is deliberately not claimed here. What is claimed is that faith and science coexisted in the founders without conflict, which answers the popular assertion that science advanced by escaping religion. The demographic point does not touch that narrower claim.
- ObjectionNewton was an anti-Trinitarian who would have been a heretic by the standards of every church of his day, and he spent as much time on alchemy as physics. Isn’t “devout Christian” doing a lot of work?
- Response
Newton was heterodox on the Trinity, and devout theist who wrote extensively on Scripture is the more accurate description. The alchemy is beside the point. The claim needs only that Newton saw his science as the study of God’s ordered creation, which his letters to Richard Bentley confirm, not that he was orthodox. A heretic who did physics to trace the hand of God is still a counterexample to the warfare story.
- ObjectionA list of believing scientists can be matched by a list of unbelieving ones: Laplace, Darwin in later life, most twentieth-century physicists. Lists prove nothing.
- Response
True, and the claim is not that scientists tend to be believers. It is the historical claim that the founding generation was largely devout and saw no conflict, which answers the specific popular assertion that science advanced by throwing off religion. The modern demographics of scientists are a separate question and nothing here implies otherwise.

Common objections
- ObjectionLewis was a literature professor, not a historian of science. Isn’t citing him for a historical thesis about the origins of science citing a popularizer?
- Response
Fair, and Lewis is stating an interpretive thesis, not reporting research. The thesis itself, that belief in a rational lawgiver encouraged the search for natural laws, is defended in scholarly form by historians such as Peter Harrison and, in stronger form, by Stanley Jaki and Rodney Stark; it is also criticized. Lewis supplies the memorable phrasing. If you want the argument with footnotes, Harrison is the place to go.

Luke A. Barnes, “The Fine-Tuning of the Universe for Intelligent Life,” Publications of the Astronomical Society of Australia, 2012.
Common objections
- ObjectionBarnes is a Christian and an active advocate for the design argument. Isn’t presenting his review as a neutral technical survey misleading?
- Response
Barnes is a Christian, and that should be said. His review was published in a peer-reviewed astrophysics journal, and its documentation of the fine-tuning cases has been accepted by physicists who reject the design inference, including Sean Carroll, who debated him and granted that the constants are fine-tuned while disputing what follows. The phenomenon is accepted across the divide even where the interpretation is not, and Carroll’s concession is the cleanest evidence of that.
- ObjectionNarrow range compared to what? The constants have no known probability distribution, so calling the life-permitting range small assumes a measure that physics doesn’t supply.
- Response
This is the normalizability problem, and it is the most important technical objection to fine-tuning. The reply from defenders such as Barnes and Robin Collins is that one can work with the range of values current theories treat as possible and show that the life-permitting subrange is tiny relative to it, and that for several constants (the cosmological constant especially) the comparison is to a natural scale set by the theory itself. Critics reply that a natural scale is not a probability. This is a real, unresolved debate among physicists and philosophers, and it is the specific dispute behind the phrase a minority of physicists dispute how the case is framed.
- ObjectionThe fine-tuning is for life as we know it. Different constants might permit different kinds of life, or kinds of complexity we can’t imagine.
- Response
Many fine-tuning cases are not about life specifically but about whether anything complex can exist at all. A universe with no stars, no stable atoms, or one that recollapses in a fraction of a second has no chemistry of any kind, and other kinds of life does not help there. For the cases that really are life-specific, the objection has force, and defenders of the argument usually concede it. The argument is strongest where it rests on the structural cases, and that is where it should be pressed.

Common objections
- ObjectionThe 1 in 10^120 figure compares the observed value with a naive quantum field theory estimate that everyone agrees is wrong. Doesn’t it measure our ignorance of how to calculate vacuum energy, not fine-tuning?
- Response
That is a fair technical point. The discrepancy is a famous unsolved problem, and physicists disagree about whether it is best described as fine-tuning or as a sign that the calculation is wrong. What is not in dispute is that if the constant were even modestly larger than observed, galaxies would not form; the life-permitting range is small on any account. Keep the two questions apart: why is it so small is an open puzzle, and it must be small for structure to exist is the fine-tuning point, and only the second is relied on here.

Common objections
- ObjectionJastrow was writing in 1978, wasn’t a cosmologist, and thought the Big Bang was compatible with both a theistic and a non-theistic reading. Isn’t quoting the mountain-climbing line without that context misrepresenting him?
- Response
Jastrow’s book is a popular work and his remark is an opinion, not a scientific result, and he drew no theological conclusion himself; he thought the question of what came before was scientifically unanswerable. His point was about the surprise of the discovery for a scientific culture that had assumed an eternal universe, and about the irony that the biblical tradition had long asserted a beginning. That is all he is cited for. Its value is limited to answering the assumption that only believers see a fit between the Big Bang and the doctrine of creation.

Common objections
- ObjectionHume’s real argument isn’t that miracles are impossible but that testimony to a miracle is never sufficient, since a mistaken or lying witness is always more probable than a suspended law of nature. Redefining “violation” doesn’t touch that.
- Response
Correct, and this is the half of Hume that the definitional reply does not reach. The standard response, from John Earman, Richard Swinburne, and others, is that Hume’s probabilistic argument, taken strictly, would rule out believing in any extraordinary event on testimony, including well-attested but rare natural events; and that the probability of a miracle on testimony depends on the prior probability that God exists and would act, which Hume simply set at zero. Earman’s Hume’s Abject Failure is the technical treatment. The evidential argument is the one to answer, and it is answered by the wider case for God, not by a definition.

Sources

Common objections
- ObjectionLewis’s thief analogy fails because the thief is inside nature and obeys its laws. A miracle by definition introduces a cause from outside the system. That’s exactly what “violation” means, and renaming it “a new factor” is wordplay.
- Response
The analogy is imperfect in just the way described, and that should be conceded. Lewis’s actual point survives the concession: laws of nature describe what happens given a closed system, and whether the system is closed is not something the laws themselves can tell you. If there is a God who can act, his acting is an input, not a breach, in the same way that human free action is an input into physical systems without breaking physics. The question is whether such a God exists, which science does not settle, and that is what the claim says.

Common objections
- ObjectionLuck isn’t a refusal to explain; it’s the claim that there’s nothing to explain. Every particular outcome of a lottery is improbable, and nobody demands an explanation for which ticket won.
- Response
The lottery point is the standard one, and the firing-squad reply answers it. What needs explaining is not that some outcome occurred but that this specifically remarkable outcome did, the way a lottery won by the commissioner’s brother-in-law invites explanation even though every ticket was equally unlikely. A universe that permits chemistry is the brother-in-law outcome, not a random ticket. The deeper version of the objection, that the constants have no probability distribution at all, is the normalizability problem, and it is taken up under the Barnes exhibit.

The multiverse

Why this supports the claim
Sources
Martin Rees, “Just Six Numbers: The Deep Forces That Shape the Universe” (Basic Books, 1999)
Common objections
- ObjectionThe multiverse isn’t an ad hoc invention to avoid God. It falls out of inflationary cosmology and string theory for independent reasons. Doesn’t “a step beyond the evidence” ignore that?
- Response
Fair. Eternal inflation and the string landscape are the reasons physicists take the multiverse seriously, not a wish to avoid design, and that should be said. The design proponent’s reply is that those theories are themselves unconfirmed, that eternal inflation requires its own fine-tuned initial conditions, and that a multiverse generator would have to be fine-tuned to produce varied universes at all. The debate is real. Trades one unseen thing for countless others is a fair summary of the cost; the physics that motivates the trade is a fair summary of the reason.
- ObjectionThere’s a fourth option missing: a deeper physical theory may show the constants aren’t free parameters at all but are fixed by necessity. Wouldn’t that dissolve the problem without luck, multiverse, or design?
- Response
Many physicists do expect this, and it belongs on the list. The reply from design defenders is that a theory fixing the constants by necessity would itself be a remarkable fact requiring explanation: why should the only possible physics be life-permitting? On that view the fine-tuning relocates rather than vanishes. Whether that reply works is contested. Treat necessity as a live fourth option, and weigh the design proponent’s response to it alongside the other three.

Sources
Robin Collins, “The Teleological Argument: An Exploration of the Fine-Tuning of the Universe,” in “The Blackwell Companion to Natural Theology” (Wiley-Blackwell, 2009)
Common objections
- ObjectionWho designed the designer? A God capable of fine-tuning a universe is far more complex and improbable than the universe, so design explains the improbable by the more improbable.
- Response
This is Dawkins’s central argument and it has to be answered. The theistic reply, from Swinburne, Plantinga, and others, is that God is not a complex physical arrangement of parts and so is not improbable in the way a physical structure is; simplicity in explanation is about the number of independent postulates, and a single necessary mind is arguably simpler than a multiverse of unobservable universes. Dawkins’s critics also note that explanations do not need to explain their explainers: one can infer a designer from a watch without knowing the watchmaker’s origin. The debate is philosophical, and both sides are worth reading.
- ObjectionDesign is unscientific in a specific sense: it makes no testable predictions and can accommodate any observation. The multiverse, whatever its problems, is at least a research program with mathematical content.
- Response
This is the fairest form of the unscientific charge. Design proponents reply that the design hypothesis does predict something, namely that the universe will look fine-tuned, and that the multiverse, in the versions relevant here, is also untestable in principle since other universes are causally disconnected. The honest conclusion is that neither design nor the multiverse is science in the ordinary sense; both are metaphysical explanations of a scientific fact. Design should not be singled out as the unscientific option, and the accurate statement is that both are outside science, not that both are inside it.

If human reason is only the product of unguided evolution aimed at survival, then trusting it to find truth undercuts itself, which is a problem for naturalism.

Why this supports the claim
Sources
Alvin Plantinga, “Where the Conflict Really Lies: Science, Religion, and Naturalism” (Oxford University Press, 2011)
Common objections
- ObjectionStep 3, that a reason to doubt reliability is a reason to doubt everything, is too strong. We can doubt our faculties in abstract metaphysics while trusting them in perception and survival-relevant reasoning, where selection pressure clearly applied.
- Response
This is one of the better responses in the literature. The reply is that the argument for naturalism itself is abstract metaphysics, so the domain restriction would undermine naturalism specifically while leaving everyday reasoning intact, which is close to the conclusion Plantinga wants. Whether faculties can be trusted domain by domain in this way is a fair question, and it is one you should weigh rather than take on trust from either side.
- ObjectionThe argument proves too much. If unguided evolution undermines trust in reason, it undermines the theist’s reason too, since theistic evolutionists accept the same evolutionary history.
- Response
The argument targets naturalism plus evolution, not evolution alone, because a theist can hold that reliable minds were intended. The fair follow-up is that guided evolution is an unfalsifiable add-on, and that is partly right; but the argument is not offered as evidence for God. It is offered as a problem for one specific combination of views. A theist who accepts evolution has a reason to expect reliable cognition; a naturalist has to derive it from selection pressures alone, and that derivation is the step in dispute.
- ObjectionPlantinga’s probability claims are hand-waving. He never gives a principled way to estimate them, and his examples of adaptive false beliefs (the man who wants to be eaten by tigers) are contrived.
- Response
The tiger example is contrived, and even Plantinga’s defenders often drop it. The stronger form of the argument does not need it. It observes that selection acts on behavior, that many behavior-producing belief systems could be adaptive, and that we have no independent way to know ours is the truth-tracking one if naturalism is true. The critics’ reply, that true beliefs are generally more adaptive, is the crux, and it is presented as such in the next exhibit. This is the weakest argument on the site by its own admission, and it should be held that way.

Common objections
- ObjectionPlantinga’s reply that selection acts on behavior, not belief content, assumes beliefs and behavior can come apart. If my belief that the cliff is dangerous causes me to avoid it, selection for the behavior is selection for the belief.
- Response
This is the strongest version of the reply, associated with Fodor and with Fitelson and Sober, and it is the one to quote. Plantinga’s response is that beliefs cause behavior by their neural properties, and it is the neural properties that are selected, so semantic content comes along only if it happens to be correlated; naturalists reply that the correlation is exactly what evolution would produce. This is where the argument stands or falls, and the debate is unresolved. You should see both moves and decide for yourself.
Claim 12
A complete physical account of the brain still does not explain why we have inner experience, and this fits a mind-first universe at least as well as a matter-first one.

The physicalist explanation, consciousness is just brain activity
1 source · 1 objection
Why this supports the claim
Sources
Daniel Dennett, “Consciousness Explained” (Little, Brown and Company, 1991)
Common objections
- Objection“A complete map of which neurons fire still doesn’t tell you what red looks like” is just the knowledge argument, which Dennett has answered at length. Stating the opposing view fairly requires stating its answer.
- Response
Fair. Dennett’s reply to the knowledge argument is that what red looks like is a set of functional dispositions, and that Mary in Frank Jackson’s thought experiment would not learn a new fact on leaving her black-and-white room but acquire new abilities. Jackson himself later abandoned the knowledge argument, which is worth knowing. The debate is not settled in either direction, and both moves should be on the table before you decide whether the hard problem is real.

David J. Chalmers, “Facing Up to the Problem of Consciousness,” Journal of Consciousness Studies, 1995.
Common objections
- ObjectionChalmers is a naturalist who explicitly rejects theistic explanations of consciousness. Isn’t using him for a theistic argument borrowing his premise and ignoring his conclusion?
- Response
Chalmers is not arguing for God, and he is used here for the premise only. That is legitimate as long as it is clear that his own solution, consciousness as a fundamental property within a naturalistic framework, is a rival to the theistic one, not a step toward it. The fork is this: if the hard problem is real, reductive physicalism is in trouble, and both a mind-first universe and Chalmers’s naturalistic dualism are ways of taking that seriously. Which fits better is the comparison the next exhibit makes.
- ObjectionIsn’t this a god-of-the-gaps argument? Neuroscience is young. “We can’t yet explain consciousness” isn’t “consciousness can’t be explained physically.”
- Response
The hard problem is not a gap in the ordinary sense. It is the claim that no amount of structural and functional explanation could in principle yield experience, because experience is not a structure or a function. Chalmers’s argument is conceptual, not an appeal to current ignorance. That argument may be wrong (Dennett and the illusionists say it is), but if it is right, more neuroscience will not close the gap. The distinction between a gap in knowledge and a gap in kind is the whole question.
Evidence 03
The mind-first explanation
1 source · 2 objections
Why this supports the claim
Sources
J. P. Moreland, “Consciousness and the Existence of God: A Theistic Argument” (Routledge, 2008)
Common objections
- Objection“Consciousness is what you’d expect in a universe made by a mind” explains nothing. Why does consciousness depend so intimately on brain states, appear late in evolution, and vanish under anesthesia, if mind is fundamental?
- Response
This is the strongest empirical objection to mind-first views. The theistic reply is that God creating minds that are realized through brains is consistent with dependence on brain states, and that the timing and vulnerability of consciousness are facts about embodied minds rather than about mind as such. Critics find that reply ad hoc. The honest framing is that the correlation data favor physicalism on the surface, the hard problem favors non-physicalism at depth, and each side has to explain the other’s data. That is a comparison of fit, not a proof.
- Objection“Fits a mind-first universe at least as well” is a weak conclusion dressed as a strong one. Panpsychism, property dualism, and Chalmers’s own naturalistic dualism all take consciousness seriously without God.
- Response
Correct. The hard problem, if real, is evidence against reductive physicalism, and there are non-theistic views (panpsychism, Russellian monism, naturalistic dualism) that accept the problem. The theistic claim is narrower than consciousness proves God. It is that a universe in which mind is fundamental is what theism predicts and what materialism does not, and that the non-theistic alternatives are also departures from materialism. This is a comparison of fit among views that all reject the materialist default.
Claim 13
Biological evolution, whatever its scientific merits, does not by itself settle the question of God, and Christians hold a range of views on it.
It is often assumed that accepting evolution means rejecting God, or that rejecting evolution is required to keep faith. Neither follows. Evolution is a scientific account of how life diversified. Whether there is a mind behind the process is a further question science does not reach. Christians fall into several camps: young-earth creation, old-earth creation, and evolutionary creation, which holds that God worked through the process. Scientists who are also Christians, such as Francis Collins, hold the last. The point for a conversation is that the science of common descent and the existence of a Creator are not the same question, and treating them as one confuses the debate.
1 exhibit · 1 objection answered
Evidence 01
Francis Collins on faith and common descent
1 source · 1 objection
Collins, who led the Human Genome Project, argues that the evidence for common descent is strong and that it is compatible with Christian faith, with God as the author of the process. Whatever one concludes, his position shows the choice is not simply evolution or God.
Why this supports the claim
This separates two questions people run together. You can dispute the science on scientific grounds, or hold it and still be a theist, but you cannot claim evolution alone rules out God without a further philosophical argument.
Sources
A scientist’s case that common descent and Christian faith fit together.
Common objections
- ObjectionEvolution explains the appearance of design without a designer, so it does make God unnecessary. Isn’t that Dawkins’s point, and isn’t it right?
- Response
Evolution can explain the diversity of life without invoking God at each step, and that is a real achievement. What it does not explain is why there is a law-governed universe capable of producing life at all, why the constants are life-permitting, or why anything exists rather than nothing. Unnecessary for explaining species is not the same as unnecessary. Dawkins moves from the first to the second, and that move is philosophy, not biology.
