Just yesterday, I was able to watch a video called, 'The Star of Belthlehem'. I was excited, thinking it was going to be a movie, or something of the sort, but was pleasantly surprised to discover it was more along the lines of a professor (an interesting one) giving a lecture. The theories presented were not only plausible, but highly probable. There is a website [link] which talks about the video, as well as the information covered and resources. It's well worth investigating.
