The Flat Earth idea is a primitive concept of the earth as a plane or a large circle.[1]

The Flat Earth Myth is an example of liberals trying to rewrite history to slander Christians. The myth was perpetrated by evolutionists in the 19th century, painting the medieval Catholic Church as "believing in the flat Earth". This was not the case however, as it was well known since ancient times that the Earth was round. This is shown by the fact that sailors would be unable to navigate properly if they held a belief in a flat Earth.

The ancient Greeks knew that the Earth was spherical. Aristotle gave some convincing arguments for the spherical Earth, including ships sailing over the horizon. When ships sail away over the horizon the mast disappears after the lower part of the ship has disappeared. Similarly the mast appears before the lower part of the ship when a ship sails towards us over the horizon. This is consistent with the Earth being spherical. During lunar eclipses the Earth's shadow is always round. Eratosthenes used geometry and a hired pace man to estimate its circumference to within a few percent.[2]

Medieval Europeans knew this, and had correctly warned Christopher Columbus that he would never get to India with his limited supplies. Columbus relied on a fallacious argument that the Earth was much smaller than the Greeks estimated.

Some writers have presented the mistaken idea that medieval Europeans used a literal reading of the Bible to conclude that the Earth was flat.[3] They supposedly tried to convince Christopher Columbus that he would fall off the edge of the Earth, the story goes, but Columbus discovered America and Ferdinand Magellan proved that the Earth was round.[4]

The Flat Earth theory was mostly invented and promoted by evolutionists for the purpose of slandering Christians.[5][6][7]
