Assuming any of these people actually existed..

Building a folklore figure of an amalgamation of deeds of many is a common historical issue.

Considering nobody was the "son of God," and nobody rose from the dead or turned water into wine etc etc, why should any of the more normal tributes of a person be believed? I'm sure that there was a person who resented the way the Judean elders were too comfortable with Roman rule and a bloke called Jesus questioned it and got nailed to a tree for his trouble. I'm equally sure that this was considered martyrdom by those of a similar opinion. The conjuring tricks and "better than the rest of us" persona is easy to see as a way to elevate his reputation.

A bit like Mohammed owning a two stroke flying carpet with performance exhaust and front disk brakes. If you want ignorant peasants to be impressed, make your hero do things they can't. It is beyond my comprehension though why intelligent educated people in the c21 can say that they honestly think the fantasy bits are actually true, whilst laughing at the scientologists and mormons.

I'll tell you what, though. I doubt any inhabitants East of the Mediterranean two thousand years ago were particularly light skinned.... Whatever they were, the classical images of such people have been fairly European, and that is just a sign of the bigotry of the time.
