Contrary to my name, I am no scientist. However I don't need to be when I am amongst people of your IQ and the topic of conversation is a theory as dumb as this. I have found a major loophole which not one of you has opened your eyes wide enough to see. The origins of this theory involved a bible verse that was quoted from God and referenced the "Four corners of the Earth". Your beliefs base on the fact that a sphere does not have 4 corners, so therefore the Earth cannot be round. However, any object other than that which is a quadrilateral cannot have for shapes, so neither can a disk. The shape you claim the Earth to be is a disk, or that of an O, which not only doesn't have 4 corners, it has 0.
Another thing, if there is no suck thing as gravity, how do things fall when someone throws them in the air? What causes them to fall and not the Earth?
