Attn: Theists - What would it take to prove you wrong?

[Esquilax]

Get back to us when you get those ideas of what proofs would work maelstrom. See you never.

That's fairly easy, though: how does one verify the existence of, say, the ace of hearts in an unopened pack of cards?

All of the things you might think of for that would apply equally well when applied to god. Existential claims are really very easy; the problem you're having is that you don't have any way to verify that your god's existential claim is true, but are desperate to hold onto it anyway. In order to accomplish this, you theists have made an art of crudely twisting logic and reality into awkward shapes to preserve your untenable belief.

Or hell, maybe you can demonstrate your claim. I'm not going to discount that possibility.
