I feel like if you knew it would defeat the purpose because you would believe only because you knew it was there. I feel like if there was a creator it would want you to have faith in it not just because you knew but because you really had faith. also I don't necessarily think its Christian god. I think all cultures have their own names and practices etc for who they believe it is. if people don't believe in religion and evolution I feel like its almost just ignorance, cause if there's a being who can create everything I think they would have no problem guiding the path of evolution. also I am not 100% sure but I think the bible was probably written before the theory/fact of evolution
