God, by definition, is the uncaused cause. Only things that begin to exist need a cause, and God did not begin to exist. He is eternal. That is not ignorance, it is a logical necessity. If there is no eternal something, then you are left with something from nothing, which is impossible. We both have to believe in something eternal; the question is whether it is eternal mindless matter, or an eternal intelligent mind. The evidence from the beginning of the universe, fine tuning, and moral law points to the latter.
