When Vala found some stones in the last few episodes of season 9 she said she got pregnant without sex and if anyone ever heard of such a thing. Everyone looked at each other and said some stupid answers, and San is like 'Really people?!?' because it was clear they didn't want to piss off the bat shit crazy fucking religious idiots in the USA, so they just never said names.
I think Jesus was really Daniel. Dan went back in time, had the time travel puddle jumper land one whom the fairy tale of Jesus was based on and so Danny boy took over the role, he died, ascended for the 195th time. and boom we have easter.
