I love how everyone always demands for proof. To quote the Santa Claus "seeing isn't believing, believing is seeing" You will have proof after you have found Him. This may seem unrational but really it's not. He can't give you proof until He sees you right? I also really love Pascal's Wager and Thomas' Laws.
For those unfamiliar Pascal's wager says that if someone told you he was going to flip a quarter and if it landed on heads you would win a million dollars. So the atheist doesn't believe it will land on heads and bets tails and the agnostic refuses to bet. The Christian bets heads. The prize of course being heaven. Or as my dad words it "It is better to believe in God and be wrong then to not and be right."
The Thomas arguements simply say that the world was put into place by a set of domino events. In order for these domino events to take place something had to push the first one and the something can't be a domino in itself. It must be an uncaused causer. or something that was there from the beginning. And So on so forth.
Anthrpologists mainly agree that Jesus existed the question is whether he is a good man or a God. Which is ludicras because if he was a good man he wouldn't have lied about being God and he obviously was a good man therefore he is God. There are so many of these arguements that as the original poster stated at least one of them has to be true.
