Full Metal Alchemist The world beyond the Gate (spoiler warning)

In episode 49, Ed gets transported to our world thru the gate, right?

Well, there's a question I've been asking. In THEIR world, Christianity was an ancient, extint religion. This could explain the stained glass and the church seen, and the letter sent by Hohenheim to Dante. But here lies the question: If their world is a different world from ours, why did they share THE SAME religion?

Did Christ die in two different worlds at the same time? Or maybe... MAYBE...

Their world is OUR world, just in the future! (This would pose several theological questions which i'm NOT willing to ask, since it would become just too complicated :glazed: )

So that means, that Edward Elric came thru the gate, into the past! (Like in the original version of "Planet of the Apes", but backwards) This would also explain why in the future people can use alchemy but not today. The gate acts as an energy tunnel, and the Entropy is not altered. The energy can flow into the future, but not into the past, so the law of conservation of ENERGY applies.

So what drives this energy? Maybe in the future, a really big, ugly experiment created the gate, or maybe it was some side effect of a massive destruction? This also poses the question, a religion would be extint if ALL its followers are dead. This seems very unlikely for Christianity, unless an apocalyptic event took place.

Perhaps we haven't seen "The Truth behind all truths" after all. What do you think?

 

Or it's possibly an alternate reality, where the timeline diverged eventually and Christianity died out.

Or it slowly died out, phased out by different beliefs (by force or not). I mean, the viking religion is pretty dead. Sure, there'll be people saying "HAY THERE ARE NEW FOLLOWERS" but it's not exactly the same.


Edit: I will admit right now I've never seen the series, but heard enough from a housemate to know the general idea. I'll ask him about his thoughts.

Secondary edit: As far as a church goes, that could simply be a case of similarity in design. The specific form of the cross isn't that uncommon (look at the Egyptian ankh, for starters, its close), and a church like structure could be developed fairly easily.
