I question whether he ever existed. I know that sounds insane in a culture built on the certainty that he did (and Christmas movies presented as fact), but the more you actually look at what historians and Catholic apologists write about the issue, the more you realise the evidence is very scant. Without the bible, there would not be enough evidence for a historian to consider him a real historical character.

As the only evidence, the new testament comes under scrutiny. The first parts of what would become the New Testament were written around 40 years (the absolute minimum according to even religious scholars) after his death. Later parts were added up to 100 years after his death. In a time of myth and superstition, without widespread education/writing, TV, or reliable press, such a story could very well be a complete fabrication. Certainly there were excellent reasons for religious powers to write a story which combined the prominent pagan myths of the day (as the bible suspiciuosly does).

Anyway, the point is that even if he did exist, we can't reliably say anything at all about him or his life, as none other than the religious powers of the day wrote anything historical about him.
