I'm amused by your assertions about how evidence works in a court of law. You have a book that asserts that there were eyewitnesses. Not a single document written by any of those eyewitnesses exists. There is no chain of evidence.
By those standards, every wild claim made in every book on UFOs, ESP, and the like would stand up in a court of law. Even more so, because the witnesses are alive and able to testify.
Conan Doyle, a very bright person who made a lot of money writing about the examination of evidence, was completely taken in by a couple of teenage girls who forged pictures of garden fairies.
The simple fact of life is that most people are fools, willing to believe in John Edwards, Uri Geller, Bill Clinton, or anybody else with good looks and charisma.
It could be that Christians are the greatest fools in the world - or vice versa. For myself, I'll go with the man who taught us love and holiness, perfection and purity, faith and hope, rejection of sin and evil, and pure unadulterated courage. Of course, if Christians are right, non-Christians may get a wake-up call...
You're assuming the Book of John was writen by someone other than John.
LOL You must be joking.
