>pretty bold claim (i.e. that a human physically came back from the dead)

I was brought up Christian and put that in the no evidence either way category. But then it turned out that

>Horus, like Jesus -- or Jesus, like Horus -- was born of a virgin, had twelve disciples, walked on water, delivered a 'sermon on the mount', performed mircles, was executed beside two thieves, rose from the dead and ascended into heaven.

Horus being a popular belief centuries earlier. And so now I think they probably plagiarized the story rather.
