"I refuse to prove that I exist" says God "for proof denies faith and without faith I am nothing"

"But" says man "the fish is a dead give-away isn’t it, it couldn’t have evolved by chance. It proves you exist and so therefore by your own argument you don’t"

"Oh dear" says God "I hadn’t thought of that, and promptly vanishes in a puff of logic"

"Oh that was easy" says man and for an encore goes on to prove that black is white and gets himself killed on the next zebra crossing.
