Theoretically an Elder scroll could help alot if not completely solve the mystery but rather obviously that almost certainly won't be scripted in by Bethesda because this whole mystery (as said earlier) is very popular and a very big aspect of the Elder scrolls lore and the dragonborn (or a moth priest) just getting an Elder scroll and revealing it would be a bit of an anti-climax.

But you are absolutely right an Elder scroll would solve this but to be completely honest it is one of those things that are meant to be unsolved.
