"You could lay down on the beach and watch a boat disappear only to stand up and have the boat come back into view. This is because the waves between you and the base of the boat "converge" into a false single point/ horizon due to the limited resolution afforded by your eyes and due to the angle in which the object is viewed. When you lay down the angle of view makes it so that the false horizon would be closer than if you were to stand up. This is perceptive." That right there shows exactly how retarded you are. OF COURSE if you are lying down and stand up your field of view is going to change, you fucking retard...you just proved round earth!! A change in elevation is a change in the geometry. If it were flat earth, the only thing that would change is the elevation, not the viewing distance, you dumbass
