While Richard Dawkins and Sam Harris appear in it, pay attention to a couple of the less public people in it such as Robert M. Price and Richard Carrier. Carrier has gone head to head with
. Robert Price has a podcast called
"The Bible Geek" where he is open to any question. Both are professors and have published quite a few good books.
The main point of that movie outrages many Christians;
There is no -- zero, zip, zilch, nada, ... -- record of Jesus Christ of the Christian Bible till well after he had supposedly died.Nobody noticed him while he supposedly was alive.
Nobody wrote about him when he was supposedly alive.
Yet, when asked for a single bit of evidence that shows that is not the case, they come up empty handed.
Note that I do not say that there absolutely is no possibility that there was a Jesus Christ as roughly described in the Christian Bible. Carrier does, but his argument is one that even he admits requires quite a bit of specialized research.
That said, as a mere mortal, the silence is deafening. You would think that if a god walked the Earth, that someone would have written a note home about it, let alone some local officials or interested historian.
So, if you introduce her to that idea, I recommend keeping it simple;
nobody wrote about Jesus till well after he had supposedly died.
That said, there are lists 'proving' Jesus lived, and they tend to use valid historians. The important detail, though, is that none of them were writing (many were not even alive) at the time Jesus supposedly lived. (Also, some of the words are considered forgeries -- additions -- such as those by Josephus about Jesus.)
