There’s religion and religion, belief and belief. “Natural philosophy” and religions that addressed the natural world through simple myths (thunder means Zeus is mad and we gotta sacrifice a cow, idk) were certainly a thing, but Judaism and Islam, for instance, talk about what lies beyond the veil, Jesus’ “unseen”, and has nothing to do with the material world. Science and monotheism are not superimposed, science is about anything you can actually have evidence for.
