The best evidence I can site, on short notice (I'm almost out of time for today, I'll try to satisfy your request better tomorrow), is the Bible itself. I've read it cover to cover 3 times, and studied it somewhat besides. It strikes me as having been man-made, I see no evidence in it of divine authorship.
As far as the OT prophecies concerning Jesus, I think they were not, in fact, prophecies of Jesus at all, but were instead an attempt to retrofit certain OT verses to seem like prophecies, and then were included in the Jesus story as being fulfilled by Jesus after the fact. In other words, the authors of the NT wanted to impress their readers with these claims of fulfilled prophecy, and so wrote the story so it would seem like prophecy was being fulfilled. I can go into more detail on this tomorrow if you'd like, I'm out of time now.
