Considering the overwhelming evidence we have for the Big Bang…wouldn’t such a belief nullify any possible theories in naturalistic evolution? Especially if we apply it to the kalam cosmological argument:
1) Whatever begins to exist has a cause.
2) The universe began to exist.
3) Therefore, the universe has a cause.
If we combine this with Leibnizian cosmology:
1) Anything that exists has an explanation of its existence, either in the necessity of its own nature or in an external cause.
2) If the universe has an explanation of its existence, that explanation is God.
3) The universe exists.
4) Therefore, the universe has an explanation of its existence.
5) Therefore, the explanation of the existence of the universe is God.
If I remember correctly, Leibnitz is assuming that Aquinas is correct in saying that the “unmoved mover” is what people call “God.”
