I still have people asking about the Zeitgeist movie. If you are not familiar with this, it is an Internet documentary of which about half is a claim that Jesus is a mythical sun god based on Egyptian myths and astronomical phenomenon. It is pretty bad but unfortunately it has become popular with certain people. I think Glenn Peoples has done a great job responding to Zeitgeist and you can get to his podcast on this topic here. At that link, you can find some additional resources that will be helpful in response. If you are interested in more, I have an article on it in the first issue of Hope’s Reason: A Journal of Apologetics.
