Belief (there's that word again) that the world was flat, was held by a few relatively small population groups in historical times. The Mayans and the Egyptians knew thousands of years ago the general shape of the world. To most primitive peoples the shape of the world wasn't important.
I don't think you're correct. Egyptians believed that world was a flat disk surrounded by water. Pretty much all early cultures believed something like this. IIRC it was the Greek philosopher Pythagoras who first postulated that Earth was in fact a sphere. It took centuries for this to became commonly accepted. Chinese believed Earth to be flat till 17th century.
But that is details anyway. The main point was that a lot of people have really long time believed all sort of stuff that is completely bogus.
