Are Creationists “Flat Earthers”?

While probably most creationists would answer with a resounding “NO” it must be admitted that there are Flat Earthers who are Creationists. These believers in the flat earth would argue that they reject evolution and the modern model of the solar system for the same reasons, and the central reason to some is the Bible.

But what is the relationship between the Flat Earth movement and Young Earth Creationism? Where did this movement come from? And are they right about what they think the Bible teaches?
