Those who don't believe Jesus was a real person: What do you think of the Shroud of Turin?

There's no contemporary historical record of such a person ever having existed. No first-person accounts, no official record. The Shroud of Turin is a fake made in the 14th. Century to fool pilgrims. For that, we have the Church record of the artist's confession, plus scientific tests done on the cloth itself. It was woven by a method not known until medieval times, from materials not from the Middle East, and applied with tempera paint. It also depicts someone with rather weirdly deformed features. Radiocarbon dating also shows a medieval origin. There is a tremendous amount of false information out there; takes a while to sift fact from fiction.
