Hey Anti-Theists! Prove Your Claim

[Neo-Scholastic]

Sorry I couldn't resist making fun of the inane "Hey Atheists..." titled threads. Anyway...

For those of you that self-describe as anti-theists, you face the same burden of proof as believers. So, please share the compelling proof or evidence that you believe disproves the existence of a god or gods.

According to Russell's Teapot, the person who is making the claim (you and other theists) should be the one carrying the Burden of Proof, not the people doubting your claim (me and other Atheists and Anti-Theists).

So the real question should be:

"Where is your evidence that God/Gods exists?"

Russell's teapot does not apply. The OP is directed toward gnostic* atheists who are making a claim that they know God does not exist.

*I misunderstood the usage of the term anti-theist in the OP but that mistake was corrected by the posts of others.
