For a touch of historical accuracy, at least three of the gospels were written by people who weren't contemporaries of Jesus. Possibly John was, but Matthew, Mark and Luke weren't.
So what we have is hearsay, largely and possibly completely from those who didn't hear any claims.
The New Testament does not profess to be a biography of Christ, it is theology. It is new knowledge and a further revelation of God. In the scholarly vein however, using Mark and other ancient writings, we can deduce that other documents did exist from which Matthew and Luke are drawn, and I believe you will find that well known and respected scholars agree on this.
Talk about 'wanna believe'. Any authority for your unusual assertion?
