THEORY 1: EVOLUTION is a CYCLE
Although we came from monkeys' we will evolve back into monkeys too. The Planet of the Apes is based on the truth.
Think about it: as we get older what happens. We get hairier; men and women alike, hair everywhere, ears, nose, moustache, places we never had hair before.
Next our spines bend, how many older people have you noticed seem to get smaller and smaller year on year. This leads to the gorilla pose.
This one makes perfect sense. How often do you see a group of dogs or cats sitting next to each other with no noises. Yet you know they are saying something to each other or communicating in one way or another. Cats only Meow to humans and dogs rarely bark at each other. Therefore they are speaking to each other telepathically. It makes perfect sense and you all know it is true.
