Hockeydude, Jesus of Nazareth existed as a human person. at around age 30 he felt a calling,(probably) corresponding to his Baptism by the so-called John the Baptist, became an itinerant preacher, preaching the "kingdom of God". he travelled to Jerusalem, went to the Temple and caused enough of a stir to be seen as a political criminal by the Romans, who executed him via crucifixion.
the above is accepted by 98-99% of historians who study the subject. there are a few that don't, they're called "Mythicists" and take the hermeneutic of suspicion to its limits. they have a larger following on the internet than they do in academia.
I'm generally accepting of the charismatic preacher and that political opponents were crucified. I'm also accepting of the idea that winners shape history, and I can't think of a bigger "winner" in Western history than Christians.
So then why did you say Jesus probably didn't exist in the first place?
