While I was being a bit tongue-in-cheek when I said "that Christ character", I was also trying to be accurate: there are people who believe Christ was 100% made-up (and lots of others who don't of course), and I don't know enough about it to say for sure.

Personally, I'm an agnostic atheist, so I'd need to see some actual evidence before I could honestly say I believe he did exist, but I'm not gonna say I know he didn't exist either.
