I get that we are talking about a vast majority of people who never traveled, at least not far. But even if they didn't travel, they were not entirely ignorant of the world because there were plenty of people who did travel that they would have encountered regularly. It's a bit like hearing Christopher Columbus sailed to prove the world was round. It makes sense on the face of it for a 9 year old, but once you start breaking it down, it's obvious that statement is somewhere between a gross oversimplification (i.e. he sailed to find a western route to China, which would necessitate roundness) to an outright falsehood. This has largely been my experience with comparing the history I learned to the history I now know.
