There are a couple of answers to this:
A: A lot of people back then were heavily Catholic, the Catholic church claimed that the Earth was flat, while others believed the Earth was round.
B: Back then, obviously they didn't have airplanes or satellites, thus people believed the Earth was flat. The reasoning of this is because, if you were to look outside right now, the Earth does look like it could be flat.
