Paul says death came through one man. If Adam wasn’t a historical individual, as most scientists and many theologians now think, doesn’t Paul’s argument collapse?

This is a live debate among Christians. Some hold to a historical Adam, possibly as a representative head of an existing population rather than the sole first human; others read Paul as arguing from the Genesis narrative as a shared story about humanity’s condition, with the theological point (that all are under sin and death, and that Christ reverses it) not depending on Adam’s biology. The claim here is that Scripture diagnoses evil as a break with God, and either reading supports that.
