Self-evident truth
That's exactly what I said - you don't believe me. Do the Google search using the words, "Did Jesus Exist?" and you'll find dozens of articles which claim that he never existed. I can't be bothered listing them all, you'll have to do the search yourself. Millions of people agree with me. No, I haven't read, "Evidence That Demands A Verdict", but yes, I read all sorts of stuff, including material in web sites which claim Jesus existed. Remember, I used to be a Christian, so I've read the Bible. I did an Alpha course, so I've seen the Nicky Gumbel videos.
The fact is, the evidence against Jesus is more compelling than the evidence for Jesus. I've considered both sides, and come to the conclusion that Jesus didn't exist.
I doubt whether you've seriously considered the possibility that Jesus didn't exist. You have the same mind set I had when I was a Christian. You've always been taught that Jesus was a real, historical person, and that's what you believe. It's highly likely that many of your friends are Christians, so that reinforces your belief. Your parents may even be Christians.
It takes independence of thought to consider the possibility that Jesus didn't exist. It's easy to conform and say, "Yes, I believe in Jesus". Have the courage to take the hard path, and you may be surprised at what you learn.
