You just confused 8000 years of post-agricultural society and culture, with medieval western Europe. Yes, people are much more educated now, because technology lets them get better access to information, but I think it's inaccurate to say there were no educated societies in the past. Think about Roman engineering. Arabic and Indian mathematics. Baghdad with its libraries. On and on. Modern people didn't invent most of the knowledge we now take for granted... we inherited it from the past, where people found it out through trial and error. Just like we discover new things now.
