Well, even if God existed, I wouldn't see why I should have to obey him. EDIT: As it is, I believe there is no God because there's no evidence for Him. That is my mental process here. This is not, however, the topic of the thread. I'm going to be quite strict, I think, about keeping this on topic - because what atheism is or is not and why or why not you should believe in God are done to death and everybody smart enough has thought up their own answers by now anyway.
