What does one say to a professed atheist when he demands proof that God exists? One could, of course, challenge him to prove that God doesn't exist—and to prove the preposterous scenario that the universe and even the human brain just happened by chance. In fact, since God is infinite, finite beings could never arrive at an indisputable proof either for or against His existence. Furthermore, "proofs" are really beside the point.

It is impossible to "prove" philosophically one's own existence—but who doubts it? Then why is a philosophical "proof" of God's existence demanded?
