Thanks for the responses everyone.
Individual: I agree with your points. It does make sense that any attempted historical narrative unintentionally reflects the historian's background, training, methodology or subjective beliefs, even if only in part. I'm not sure how I can be curious but not ultimately care, but I do know that's how I feel. I guess what I mean is that it would be cool if I could demonstrate such proof in discussion with my Christian family when the topic comes up, but even if I'm unable to, that doesn't mean I will stop practicing. I know for sure I would not practice Christianity even if proof of Jesus the Annointed One could be adequately demonstrated because I don't agree with the teachings of Christianity (and because there would be no reason to follow him as opposed to many others just like him, since there's nothing making him better than the other "saviors.")
David: Yes, indeed. There is strong evidence that the narrative of Jesus is plagiarized from the worship of Dionysus. Even more interesting is the near universal tradition of ecstatic dance and worship, which, when observed from a historical and modern day standpoint, resembles closely the worship habits of today's fundamentalists and born-again Christians (speaking in tongue, for instance).
Sobeh: The three sources of historical documentation of Christ are exactly what I was referring to when I said the few sources of his existence are known to be unreliable. I'm no historian so I can't back that up, but I will say I've read that on a number of occassions. And as a matter of fact, I've read documents quoting Christian apologists from a few hundred years after Jesus and them admitting that, in order to convert various pagans from other lands, they had to equate Jesus with various sun gods because the stories were nearly identical.
But yes, it's interesting to note that the Buddha is mentioned in the literature of other practices. I can attest to that myself, having studied and practiced Sikhism for some time and reading the Sri Guru Granth Sahib where it mentions on a number of occassions the order of Buddhas. But to my knowledge, isn't Jesus mentioned in the Quran?
