Can't prove the supernatural God

[SteveII]

Which Paul are you talking about, exactly? Historians can only generally agree that about seven of the Epistles traditionally attributed to Paul were actually written by him, and those seven do not reference the humanized gospel story at all; in fact, looking at just the letters that Paul actually wrote, it appears that Paul himself believed in a purely celestial Jesus character whose battles and sacrifice took place somewhere other than Earth, and about whom knowledge could only be gained through the visions and writings of prophets (as opposed to history).

Your assertion here seems to be that the New Testament is a compilation of evidence about a series of claims that had already been made and circulated by the time the NT was actually written/compiled. I disagree. The New Testament is a catalog of religious claims that were being made by a particular religious group at a particular time in history; it does not actually offer any evidence for those claims. What's worse, various parts of the Bible are flatly contradicted by science and/or history (The Flood, The Exodus, The Origin of Man and the Universe, etc.). When some parts are unsupported by evidence and other parts are outright contradicted by it, the reliability of your document starts to dwindle considerably.

Thinking that idea Paul believed that Jesus wasn't real is nonsense. He mentions him in every other paragraph and the resurrection in almost every chapter. Just because he didn't mention facts about his life means absolutely nothing. He was writing to churches that already had basic beliefs. His focus was on doctrine and christian living. He also met with and corresponded with people who did hold the belief that Jesus was real. You think that Paul not believing them on so important of a point might have come up? 

The NT does not just catalog the claim. It talks of real people, real eyewitnesses (by name), and a church that was growing quickly all within the same generation of Jesus. It is evidence that the first generation believed "the claim" (from above). The epistles are written well within the memory of eyewitnesses (some by eyewitnesses themselves). The gospels are written as the generation of Jesus was dying off. The thing about generations is that they overlap. There is an unbroken chain of belief about "the claim" all the way to today.
