Jesus' existance is a matter of question, though I think there was a person who inspired followers around that time. For one, Jesus was called Jesus of Nazareth, but the prophecy says the Messiah was to be from Bethlehem. And wouldn't you know it, in three of the gospels we have a story that puts him in Bethlehem. A story whose premis is not found anywhere outside the bible mind you.
In my opinion, this "Jesus" fella was probably a very radical and progressive preacher for his day, though I don't see any reason to believe he was more than human.
