there is no real written evidence of jesus having lived when he was said to, contemporary with his 'lifetime.' as the movie says, what little (3) of texts by historians contemporary with jesus there are refer only to a 'christ,' or 'anointed one' and that could have been anyone deemed holy or enlightened or even noble in that time. the gospels and everything in the new testament were written at least 100 years after jesus's supposed death. that's why each gospel varies, and many gospels formed by different christian sects differed so greatly that the church, when it formed as a centralized political power, left most of what was written about jesus OUT of the bible. really, there is no evidence outside of the bible that he existed, and the bible, as a compilation by the early roman church (council of nicene), is a bit biased lol. jesus's birthday does coincide exactly with the beginning of the age of pisces, and every event of his supposed life does, irrefutably, mirror events in the lives of prior solar death/resurrection gods. i've been studying egyptology and world mythology, out of a genuine and objective interest, since middle-school, with interest in it since my earliest memories- im even now taking an 'ancient egyptian and mesopotamian mythology and religion' class at my university- the professor had never heard of Zeitgeist, but everything discussed thus far supports its findings perfectly.
now, jesus's non-existence as a man does not diminish his spiritual value and worth- it doesn't change his teachings, what he represents, what his cosmic/divine function is. the fact that he's an archetypical symbol or character could only offend those who accept only a surface-level approach to the bible- i say leave them to their sullen and unsupported denial of the facts stacked high against them. petty, but people will esteem what they will, for better or worse. we're all free to believe what we want, and if the passion and Will of a person in approach the divine is great enough, it doesn't matter what beliefs get them there. but please, attempts to validate or support the idea of jesus' being a historical figure are really very frail and frantic.
