Also, even if there was a man named Jesus, who had several followers and was executed, there is still no extra-biblical evidence of the miraculous events that allegedly occurred. For instance, the saints rising from their graves and walking into town.Also the people you mentioned were either not contemporary to Christ or the writings (particularly Thallus) are heavily disputed.
Assuming there was a historical Jesus then I see the Bible as being a bit like the film Abraham Lincoln: Vampire Hunter. Based on a real person but with some creative additions. I know there is a slightly more fringe theory that suggests that there was no historical Jesus, but I don't think it really matters either way.
