Here's the deal. God can prove to me that he exists by winning the lottery for me three times. I'm going to play Powerball up to three times. The odds of winning a jackpot are 1 in 175 million. If I win the first time I play, that would be very lucky. I'll play again, though, to give God a chance to prove it was him, not blind chance. (If I lose, I'll stop playing, because why throw good money after bad?) If I win the second time (odds of winning twice are 1 in 175 million x 1 in 175 million = 1 in 30,625,000,000,000,000), I'll be agnostic. I'll think, "Maybe that was God." The odds of winning all three times are about one in 5,359,375,000,000,000,000,000,000 (1 in 175 million x 1 in 175 million x 1 in 175 million), so if I can do that, I'll consider it a miracle and personal proof of God's existence.
That would convince me that there is a God. Here's my promise: if I win three jackpots in three tries, I will believe in God, tell everyone my story, and put the money to good use (i.e., I won't spend all of it on cars, hair plugs, and sugar babies). If there is a God, let's see if he's willing to step up and prove it. (I won't hold my breath, though.)
Edit: Tried to fix the math.
