Why?

[fadetree]

Ok, I'd like to be an Atheist. Seriously. It would help if someone could tell me how they *know* a god or gods don't exist. As an Atheist, I'd believe strictly in reason. Therefore, note that lack of evidence for is not evidence against, so all arguments beginning with 'We don't need a god to explain..' don't count. For the same reason, emotional arguments about why would we suffer if God was good, etc, don't count, as the question is not about the nature of God or gods but the existence of them.

Go.
