It was stated in ACIII that, if enough people believe in the illusions created by a Piece of Eden, those illusions would become real. So presumably, when Moses created an illusion of the Plagues of Egypt or the Red Sea parting, the collective belief of the Israelites made it real.
I doubt we'll actually be playing through the events of the Exodus. At best, it would be a prologue, with the main story taking place sometime after.
As for Jesus:
1- His corpse was stolen by his disciples, who tried (unsuccessfully) to ressurect him with the Shroud.
2- I'm pretty sure that it was still him who died on the cross, I don't recall any AC sources claiming otherwise.
3- There are no sources stating that the Ahnk was ever in possession of Jesus or his disciples. As for the Ankh's abilities, it was stated to have ressurected Osiris for only a single night, suggesting that it couldn't ressurect anyone for longer than that.
