Buddhist atheism is a bit different - the existence of god(s) is irrelevant. I wouldn't become Christian is Jehovah himself appeared and demanded worship. If such beings do exist, they are attention addicted ego-maniacs, whose attachment to worship binds them in suffering. I don't worship god(s) because it is neither necessary nor helpful, not because they aren't real (though they aren't, as far as I can tell).
