How about prophecy? Doesn't the multitude of fulfilled prophecies in the
NT and history written in the OT and NT imply that there might be
something unusual going on? It really is a huge number of prophecies. And
we do have manuscripts of the OT previous to 1AD, so you can't argue they
were forged. And how about the agreement between so many different authors
in so many different situations and times and styles?
On a related note, a Cambridge atheist geologist I spoke to yesterday
seemed to be under the impression that there was a flood 6ka ago. She was
vehemently opposed to Christianity, but seemed to have been taught this by
an atheistic faculty.
