Hi mP,
"Even Paul knows nothing about Jesus the man. scan thru all his writings and write down the facts you learn about jesus."
It is amazing that one can spead a life time reading the Bible and not see obvious details like this. Only after I left the faith for several years, did I finally watch the documentary The God Who Wasn't There, by Brian Flemming, wherein I saw this point made for the first time.
Since then I have thought about this argument. I will say it is interesting and is something that could support the notion that Jesus never really existed. However, I think there are a couple reasonable ways of explaining this issue. Paul generally wrote letters to congregations of believers, who would already know the back story of Jesus. As a writer, his style does not seem to be one of historical reflection, but instead on knowledge of God wrapped in the Christ (Col 2:3).
Paul is introduced to us in Acts, which is really a continuation of Luke, that is of course one of the gospels that has the life story of Jesus.
Finally, I would think that a need for a written narrative of the life of Jesus would grow as the eyewitness period was ending. This, could be the reason why the first Christian writings are Paul's letters, followed by the 3 gospels (Matthew, Mark and Luke).
Cheers,
