If no Jesus ever lived, then there is no basis for my Christianity. 
I admit it's arguable that he never lived. 
I hold that, that he did live, is the simplest way to account for many things we do know,
beginning with the apparent fact that the Christian movement appeared ca. 30 C.E.

There is one more bit of evidence that is, for me personally, conclusive. 
In 1983-84 I was having a specific difficulty pertinent the practice of spiritual healing. 
I wound up on the phone with a person whom I take to have been
the foremost American clairvoyant healer of her time. 
She told me, "Never [do that].  Jesus never did that." 
So I said, if she said that — well, that's that.

It puzzles me that it seems to be so important — to you — that he did not live. 
Suppose there was once such a person, quite possibly little different from you or me. 
Would the world be different?  If so, how? 
How would your worldview have to change?

I still think the real issue is precognition.
