Is Christianity Illogical?

[FallentoReason]

If so, please explain why. If not, please explain why a logical person should still not become, or remain Christian.

1) Christianity is dependent on an earthly Jesus
2) To date that still can't be proven
3) Therefore it's illogical to believe modern-day Christian doctrine... From ANY of the 30 000+ denominations.

Alternatively, you could explore the possibility that your interpretation is wrong and you don't know the true message of the Gospels or even their intentions.

The task for us is simple: Prove any prediction an author of the Old Testament made false, and you've proven him a fraud. Should we take Moses up on his challenge?

I would absolutely love to. Question though, what will happen after I show you trivial events in Jesus' life are almost word for word from the OT? Let me clarify here: trivial events NOT prophecy.
