The problem with Flat Earth theory is that it doesn't account for the curvature of the Great Turtle's shell. I mean, the horizon obviously proves that we're living on the back of an enormous tortoise. But we can't expect the masses to understand such subtle nuances, so why even try explaining it to them? (snicker) The truth is that if you were to sail all the way over the edge of the Great Turtle's back, you would simply land onto the back of an even greater turtle; it's turtles all the way down! #Joking
