Same here, I think that a Preacher/Teacher/Rabbi whatever, called Jesus of Nazareth without doubt existed, otherwise why would the writer of the Gospel of Luke have to invent the story of his being born in Bethlehem because of a fictional Census ? If he was making up his story, just say he was born in Bethlehem, but no, people knew he was "of Nazareth", hence the story, so those people that knew he existed would have a reason to believe his birth took place in Bethlehem.
I think Sea breeze above misunderstood what I meant, I said all we knew about Jesus was Fiction, and that is correct, but not all the content of Fictional stories is "false", they quite often contain accurate sections on various events and conversations, so some of the content of the Gospels may be of that nature, but none of it can be claimed as truth, in the sense I am using the word, for lack of corroborating Evidence.
