David Fitzgerald on the Historical Christ

I recently watched a video that brought up a few interesting points on the origin of Christianity and the Bible. The information was presented by David Fitzgerald who received a degree in history at the California State University and has been studying the historicity of Jesus for the last 10 years or more. Some of his points are as follows:

1. No historians or authors that lived during the time of Jesus wrote about him or any of the many amazing things that should have been recorded if people were taking notes. It wasn't until about 100 yrs after that people started writing about his life. 
2. The people who are often stated to have been witness of Jesus all lived way after he had died. 
3. Quotes by Flavius Josephus in his book Antiquities of the Jews (93-94AD) that support the historicity of Jesus are generally accepted by the scholarly community as forgery.
4. There were more than 40 gospels written but only 4 made it into the Bible because they beleived the earth was flat and held up by 4 pillars. 

Interesting information that may require more investigation.
