You realize that your characterization of the evidence for the existence of Jesus Christ can be applied to the evidence for the existence of Socrates?  The only evidence we have that he existed is stories written long after his death - by his students.  As for Jesus Christ, his crucifixion was probably sometime between 30AD and 35AD, and the gospels were likely written between 60AD and 90AD.

As for evidence of God - there is no evidence only if you dismiss the historical reports of the acts of God and His prophets.  Certainly you're entitled to do that, but that is a philosophical choice, rather than an evidence based choice.
