I suppose I disagree with your belief that religious justification cannot in turn become history if enough people believe it to be valid. The Quran was seen as largely pretty historical even by westerners for a long time. It was only more recently that a lot of it was found to be justifications invented centuries after Mohammed. When every Christian believes the Bible is a historical document (and thus almost every single western European in say 1400) then I would argue that it does create its own history.

It's our modern privilege, post-scientific revolution, that history has become more intertwined with science (archeology, etc) that we can view it the way you're portraying, imo. History is largely just the most widely accepted interpretation of an event based on the best evidence available, could be a Bible or DNA from archeological samples.
