Who are flat-Earthers?

Correct answer is people who believe that Earth is not ellipsoid as the science proved, but flat.

Explanation:

This theory dominated in Ancient period, even in Middle Ages, when this theory was supported even by the church. On the other side, even in the period of Ancient Greece Eratosthenes realized that the Earth is not flat, but it was until 16th Century when scientist started supporting it furthermore. Magellan's journey and the works of Copernicus and Galilei helped the spreading of scientific results.

Still, there are some people who don't believe that Earth is ellipsoid, but flat.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
