Did Xenu really exist 75 million years ago?
I can't prove he didn't.
Was Mithras of Persia created when lightning struck a rock?
I can't prove he wasn't.
Is "Bob" a piece of PD clipart that a bunch of nerds pretend is a deity?
YES! I KNOW THIS WITH ABSOLUTE CERTAINTY!
To misquote Mark Twain, faith is believing what you know ain't so. And I know "Bob" ain't so. And that's why I have perfect faith.
