Hypothetically, if governments wordwide just suddenly became authoritarian and deleted all records of history, you and some survivors escape to a remote area outside of government control, they all can’t remember much from history (either didn’t pay attwntion in class, or suffers memory loss from the governemtn attacks) and so you are designated as this community’s official historian. How much can you remember? What’s gonna be the official narrative of your little rebel community?
I’d argue if you taught someone history and never mentioned the Bible you’ve left out an important chunk of history.
Besides it’s about as whimsical and fantastical as all history of that time period was.
