This. It wasn't even particularly veiled, with a myriad of obvious parallels.
However, it isn't quite what the OP was asking, which is more akin to why they never showed the roots of our
Christianity (or any of the monotheistic religious) to be directly rooted in alien activity. Instead they went down the parallel Origin path. However, by intertwining the King Arthur, Holy Grail, Ark of the Covenant, etc themes, it was still pretty much done as closely as possible without offending too many people.
