What is Atheism?

[Whateverist]

I'm confused isn't the lack of a belief in a God and not believing in a God the same thing? You ask the question is there a god aren't both of them going to say no? And if one says there could be a God doesn't that turn it into agnostic?

I think to say "there is no god" implies you know just what they mean and in fact have sufficient evidence to establish it isn't true.  I don't know just what they are claiming this god-thing is so I don't know how one would know if it does or doesn't exist.  So I don't make any claims at all about gods, but that doesn't stop me from reporting on my beliefs.  No I don't believe in 'x' whatever they think this may be.
