It is quite popular in fiction, bit it is not well-regarded in history or theology. The reason is it is pure speculation. Eg. you might posit when Jesus walked on water, it was actually ice. Sure, this makes the story more believable, but you have no way of proving this was the case, and it is clear our best sources did believe he actually walked on water. You might just as well claim the event never happened at all and is just a legend - you cant prove that either, but it is just as believable (if not more).
