Given the dating of the gospels, how were the writers potential eye witnesses?
My fundamental issues here are that there are no eye witness accounts of Jesus's life. All of the biblical accounts are after the fact renditions or plagarisations of a legend they have heard, and most importantly were incentivized to believe.
There are numerous writings from the time that are dismissed as fictional, (Gospel of Thomas anyone?) on what basis are they any less or more reliable than the conventional gospels? If they can be so easily dismissed then why can't conventional biblical texts be?
Why is Jesus not mentioned by any of the contemporary writers who were active at the time of his supposed life? (I included a list at the start of this thread)
I can go on but you get the point without going into tedious specifics.
Coming away from the specifics of the Bible, I take wider issue with the idea within your field that because this is labelled a 'fringe theory', theologians seem unwilling to even talk about it. I could understand that would be the case for say an evolutionary biologist who suddenly came to believe in creationism, however in a field focussed on history and literary criticism, it seems a little restrictive...
Again I'd understand it if the evidence were so convincing that no comebacks were ever possible, however the only real argument I have heard when you get down to brass tacks seems to be that if we dismiss the existence of Jesus, then we have to dismiss the existence of some other early figures in history that we currently take for granted, as they are based on similar levels of evidence.
My answer to it is 'ok, let's call into question the existence of other historical figures then'.
Surely you can see how that argument doesn't support the existence of Jesus, it just potentially undermines the existence of (some) other historical figures?
I'd also argue that for the relatively obscure historical figures that are dragged into this argument, there was very little incentive for people to fictionalised their existence, as they wouldn't really benefit from it in any way, however I think it's fair to say that early Christians were strongly incentivized to argue that Jesus was a real person who actually lived.
