Did Jesus Begin as a Myth?

A conventional perspective on Jesus is that he was a real man in Galilee who had some followers, but that later on supernatural elements and outlandish stories became attached to this real figure.

But evidence suggests the development of the Jesus character happened the other way around. The otherwordly, god-like qualities appear to have been there first, and only later did historicity become added as one of his attributes--and quite clumsily.
