Do You Have Any Evidence for Atheism?

[DaveD]

Agnosticism is not saying you can't know, but that you are not sure either way.

Whereas atheists claim God does not exist, irresispective of whether they feel they have evidence or not.

Some atheist claim that no gods exist, but not all by any means. Most of us simply can't see any reason to believe in your, or anyone else's magic sky pixie.
You, on the other hand, are an atheist using your limited definition, as by asserting your own deity as the "one true god", you are explicitly denying the existence of all the others.
