Bable Fish argument.
"I refuse to prove that I exist," says God, "for proof denies
faith, and without
faith, I am nothing."
"Oh," says man, "but the Babel Fish is a dead give-away, isn't it? It proves You exist, and so therefore You
don't."
"Oh, I hadn't thought of that," says God, who promptly vanishes in a puff of logic.
"Ah, that was easy," says man, and for an encore goes on to prove that
black is white, and gets killed on the next zebra crossing.
Most leading thinkers claim that this argument is a load of dingo's kidneys.
