I don't believe in any religion either. Exactly, if any credible evidence could be provided I would accept it, and so would science. I am open to the idea, but until it can actually be demonstrated it just remains an idea. Atheist do not claim that God does not exist, they reject the claim that one does exist because theist have not met their burden of proof. I do not know if God does or doesn't exist, but you can only believe or not believe in a god, there isn't an in between.
