Why Did People Used to Believe the Earth Was Flat?

People thought the Earth was flat because that's how it looked. When you're standing on a plain or looking out to sea, everything seems flat, like a big, round table. But when people started sailing far away and saw the sun go down behind the horizon, they wondered if the world might be bigger than it seemed. Some thought the Earth was a flat disk with the sky above it, but others imagined it as a ball in space, even back then!
