Then why do the bottom of the buildings appear to be lower than the horizon? Because of curvature that's why.
Lmfao.
Anyone who thinks the earth isn't flat, http://www.iflscience.com/space/what-would-happen-if-earth-was-flat/. It is impossible for a object the size of a planet to be not "round", gravity will cause it to form back into the form of a ball, hence why objects in space are all Rounded.
Anyone who denies that I have to believe is mentally ill, such as notbatman. Even bridges we built today take into consideration the curvature of the earth, same for buildings etc or they would break apart
