I'm just going by what they said breh, this special was like almost a decade ago, they didn't talk about his religious impact, and the conclusion was while he may have been real most of the stories and conventions about him were untrue. Now maybe it's been debunked since then, or it was too controversial a position with not enough hard evidence or whatever. But honestly who really cares in the grand scheme of things. If you believe in Jesus as the Son of God or as a Prophet, nothing will convince you he doesn't exist and if you don't believe in Jesus, nothing will convince you he does.
