The existence of a cult populated by people who would have been aware of whether or not the personality upon which that cult was based ever actually existed is fairly strong evidence. This was not a cult which sprung up far from where the man lived. It was exactly where he lived and the members of the cult were his contemporaries. I simply do not buy the argument that they were somehow confused about his existence. They would have been eye witnesses and they were convinced.
You are free to believe otherwise. However, I see the denial of the existence of the man as pointless.
The problem here is that you have a different definition of "Evidence" than I do.
You have Mark, who wrote in the 2nd century, and got a lot of stuff wrong. He was definitely not a Jew, given his ignorance of Judean Law and Geography.
You have Luke and Matthew, who plagarized Mark (90% of Mark appears in either Luke or Matthew).
You have John Drinking the Bong Water. But as weird as John's Gospel is, most of what we call modern Christianity comes from John.
Now, keep in mind, a visit to a sight like SNOPES.com will show you just how fast bullshit legends can evolve and be believed by millions of people with no evidence. For instance, everyone and his brother will tell you Richard Gere had a gerbil extracted from his rectum, but that simply didn't happen.
