C.S. Lewis called it "chronological snobbery" if one thinks that something from a pervious age was stupid, just because it was old, or because they didn't have a modern understanding of certain scientific principles that were discovered later.
I'll go farther and say the average person in the Bronze Age was probably smarter than the average person today.
1,000 years from now, we are going to look awfully fucking stupid by comparison.
Bronze Age, that was like the time of Moses. I think people knew a lot more back then, as they were so close to the flood, rebuilding earth from the ruins of the world that was destroyed, so they had some humility.
