It’s more complicated than that since I do believe God exists but in a way that is incomprehensible to humans, and, according to all evidence, doesn’t “intervene” with the universe. I say “intervene” because God, as classically described, is simultaneously incapable of intervening and incapable of not intervening. If we define God as “an omnipotent being”(which, for the record, I do not), then He is necessarily also all knowing and exists outside of the limitations of time and space. Such a being would be perfectly optimized as well, and so it would be impossible for anything to occur without its express permission and cause. Therefore, under classical theism, it seems impossible for God to say, answer prayers, because this would imply that He could possibly change His mind or that what was happening wasn’t already what He wants to begin with.
