IMO the primary reason for why Rome fell was due to an inability to adequately perform regime succession without debilitating civil war. Even when they didn’t have a civil war to decide the next emperor it was too often a precarious strength sapping situation for the new emperor.
then there’s no room left for historical analysis. Civil wars, disease, currency debasement, elimination of the middle and farming classes, corruption, etc., all become irrelevant. There’s nothing left to teach.
For me history is studying the nature of man and it isn’t pretty, but it is interesting.
Throw God into history and you see design, not randomness.
Regarding science, I think George Washington Carver said it well:
“When I was young, I said to God, ‘God, tell me the mystery of the universe.’ But God answered, ‘That knowledge is for me alone.’ So I said, ‘God, tell me the mystery of the peanut.’ Then God said, ‘Well George, that’s more nearly your size.’ And he told me.”
― George Washington Carver
