This whole topic can get pretty meaningless. At what level does Jesus get to exist? Born of the Virgin Mary? Well no, that's just myth. OK, born of Mary and Joseph? No, not necessary. From Nazareth? No, not necessary. Wise men, shepherds, no room at the inn? No, just detail. Impossible to substantiate. Slaughter of the innocents? No, some stuff in Bible is just made up, possibly. OK, what about all the miracles and stuff? No, no, no, we can't be expected to prove any of that bollocks. So the crucifixion, rising from the dead, everything else? Well that kind of thing is just down to faith, innit?
What's left? A bloke, possibly called Jesus, who liked fish?
