When interdimensional creatures visit this planet (which they do), they see you as two-dimensional black and white stick figures on a piece of paper. Humans, in their arrogance, especially intellectuals, say to them, "We are capable of thinking anything we want to. We can think above the piece of paper." That's funny to them, since you don't even know what dimension you're in! You don't even know you're not in color! They see this and they leave. There's nothing here for them and they can't communicate with a cartoon. That's what linearity does to you and you're not even aware of it.
