No one is under any obligation to "prove it isn't". It's meaningless.An atheist believes (he cannot empirically or philosophically) that God does not exist.
Atheism is a faith belief then.
Tis what it is, yo
That's incorrect. I don't have faith that their is no God. I have no evidence that there is a God. Atheism is not faith based. It is the opposite of faith based. Religion is faith based, and cannot stand on its own merit.
You cannot empirically prove God does not exist, nor philosophically, so, yes, you believe on faith that God is not.
Tis what is.
For example, I actually can empirically prove the gods don't exist. Prove I can't. See? Disprove my disproof of your gods.
I don't conceive of my lack of belief in your gods as a belief as much as I conceive it as a conclusion based on the asserted models out there and the lack of evidence to support those assertions. As an example, one can't really consider oneself as having the "belief that Invisible Pink Unicorns don't exist". It's just a fact that there is no evidence that such entities exist or have ever existed, and only those who would assert they do are required to support the positive claim with evidence.
