This I Believe There Is No God PENN JILLETTE

[Towlie]

10. I can prove that God doesn't exist to anyone who can prove to me that Godzilla doesn't exist.

The ability to prove something to someone depends upon that person's standard of proof, and there are some to whom you can't prove water is wet.

But if I encounter someone who can prove to me, to their own satisfaction, that Godzilla doesn't exist, then I'll make good on my promise. Otherwise I'll stick with maintaining that there's no reason to believe that God exists (or that gods exist), just like there's no reason to believe Godzilla exists.
