Atheist vs agnostic

An atheist denies the possibility of gods.
An agnostic states that we can't be 100% sure there are no gods.

Something does not become a possibility simply because someone believes it.
If someone claims to believe in a god made entirely out of guacamole, we need give no credence to the belief because it is ridiculous. I hold all religious beliefs with this same incredulity.
I hold no more belief in the god of Abraham than I do in the god of guacamole.

Agnostics have told me, "You can't be 100% sure there are no gods."
Actually, I am 100% sure there are no gods. I find the idea of gods to be infantile, a kind of need to be protected or led, a lingering evolutionary need for a strong tribal leader.

All gods that can't be seen, heard, or sensed in any scientific way, are indistinguishable from non-existence.

I can't think of one reason why I would call myself agnostic.
That would be using religious logic that asks me to, Prove God doesn't exist!"

The burden of proof is not on the atheist, but on the religious person... or the agnostic... to show any evidence for the existence of a god.

With a total lack of evidence, I fail to see how one could claim any chance of the existence of gods.

I'm an atheist.
There are no gods.
