I have this theory that's rather complicated but listen.
You, me, all of us; we only believe what we have been told by others. Example: If I point to a clock and I ask you "Well what is that?", most likely you are going to tell me "A clock." And see that's the thing, who says that it's a clock? How do you know for a fact that the clock is a clock? If the person who said a clock was a clock was crazy, or maybe even just stupid, well then that person has got everyone in the world to believe the stupid and crazy "fact", that a clock is a clock. This theory works for everything really. Who said a hairbrush was a hairbrush? Who said a finger was a finger? So, my theory is that nothing at all in this world is what we think it is.
Did that make any sense?
