OK, I am offering $10E+12 to anyone proving that God is real (of course, I don't have $10E+12, but the same holds for proof of Divine existence).

Please note that "If God does not exist, who pops out the next Kleenex?" does not constitute the proof in this context. Neither does "I feel Divine presence" nor "It says so in the Bible".

Edit: I appologize to genuine believers here and hope they are not offended. Their faith it just that, faith; we are talking proofs here (which are more or less irrelevant for religion, but not for science).
