Mujus, while I do appreciate your willingness to bring so much great material to the table (and I do truly appreciate it), I do not appreciate your unfounded assumption that my positions are just "preconceived notions", not founded on actual research. You seem to be assuming that, because my conclusions do not coincide with yours, that I have not devoted sufficient time to analyzing these questions to land at well reasoned conclusions. On the contrary, I have devoted a great deal of time to my studies. Having grown up in a household with a Catholic mother and a Lutheran Father, these morality stories had been with me since birth.
I have previously read the overviews on bible.org and have found them to be pretty lacking in verifiable evidence. For the most accesible example: the page that you reference begins with a "Background of Paul". This biography is pretty straightforward and sticks pretty close to the biography I learned back in Catholic Sunday school. However, I could construct a similarly detailed biography of Achilles using references from the Iliad, the Odyssey, several ancient tragedies, and other fragmentary texts. Does that make it historically accurate? No. There is no archeological evidence that backs up a Trojan War so there is no reason to assume that any of the heroes portrayed as participants should be taken as anything other than legend. On the contrary, the stories of Alexander the Great seem fantastical but we do have archeological evidence of his campaigns to India so, while we may not take every anecdote about him as historical fact, we do pretty much unanimously agree that he did exist. Paul exists nowhere outside of his epistles and the story in Acts. There is no archeological trace of a wandering evangelist of the influence that the Pauline epistles suggest.
Jesuscentral.com is new for me but, on hopping over there to check it out, I follow the link to "Eyewitnesses who saw Jesus" and the first link on the list is for Paul. Unless I'm much mistaken, Paul isn't even considered to be an eyewitness to Jesus in the most literal conservative reading of the scriptures. Paul didn't come to Christ until his mystical conversion on the road to Damascus, long after Jesus had shuffled of his mortal coil. A quick survey of the rest of the site reveals no sources from outside of the bible aside from Josephus and Tacitus. A quick search online should give you ample evidence that the legitimacy of these two passages is greatly debated across scholarship. A particularly well-researched and well-reasoned online version is at http://www.earlychristianwritings.com/testimonium.html (and, while the author generally lands on your side of this debate, in this instance the evidence is just too strong and he finds at least half of the Josephus material to be too far gone to be acceptable). I happen to find the questioners to have the upper hand, you find the accepters to have it. I doubt we're going to convince each other on this point so we'll just have to let it stand as is.
However, I can't take the rest of jesuscentral seriously for the simple reason that it is a primary tenet of logic that you cannot prove a premise by using that premise, aka circular reasoning. Trying to claim the historical validity of the bible by quoting from the bible will not stand up to even the most generous of scientific scrutiny.
I do not object that the sites are Christian. I object that they presuppose articles of Christian faith to support their proofs. To suggest that old testament prophesies of a messiah somehow proves the existence of a historical Jesus is asking a bit too much for a reasoned debate.
Evidence isn't something that needs to be accepted. It's something that needs to be corroborated. Otherwise it falls into the category of hearsay.
