All origins systems are underpinned by unprovable presuppositions, including atheistic origins accounts, the biblical origin account, and so on. Origins accounts have to be logically compatible with science and have explanatory power. Philosophical uniformitarianism is an atheistic presupposition. It is more in the realm of philosophy than science, yet it has a significant bearing on how atheists interpret scientific evidence, especially in the origins domain.
