By definition, atheism is the belief that God does not exist.
On Topic: As a non-atheist I'd just like to point out that these [s]debates[/s](Really, this forum doesn't have the ability to strikethrough...?) rants are very pointless and never get anywhere.
The only way to prove either side is by empirical evidence, and at this point, neither side has, be it scientists, philosophers, theologians, etc.
Also, I'd like to point out that faith is based on spiritual apprehension rather than proof, so starting threads like "A Question to Atheists" is very pointless.
P.S.
An atheist searches for God like a robber searches for a policeman.
inb4 a theist searches for God like a child searches for Santa
