I didn't look at the recent posts, but as for the original post...
It will be hard for you to be swayed to believe in the validity of the New testement by this...however Christians (like me) believe that the Holy Spirit talked directly to the men and told them what to write...
On a more practical level, at least practical to your beliefs...
Today experts (both NonChristian and Christian) say that the gospels were passed by word of mouth and then only about 25 years after Christ's death...and ressurection (depending on your belief). The authenticity of Herodotus and Thucydides is never questioned despite the fact that the earliest manuscripts of their works that we used were written 1,300 years after the originals, which were presumably lost/destroyed.
There are many examples like this including The Iliad etc.
There is also the internal evidence in verses like Luke 1:1-3, 2 Peter 1:16, 1 John 1:3, John 19:35, and Luke 3:1 obviously too many to type out at this moment, though I would be more than happy to if there is more interest in this.
