There is no proof that Jsus ever lived. It is far more likely that he never did (unless he was some obscure guy who didn't do any of the things mentioned in the GT).

None of the historians of the day mention him. None of the Roman records mention him.

Xians will say "he was unimportant so that is why the Romans didn't mention him" but how can you say a man with thousands of followers (remember the fish and wine bit?) go un-noticed?

How about earthquakes? Unrecorded.

Dead people walking around? Unrecorded.

There is nothing outside of the GT that even hints to such a person.

I suggest you read the Jsus Puzzle.
