we are rules by instinct, what are you talking about. We all have the instinct to survive, most to breed, etc etc. Just because we allude ourselves into thinking there is some greater mechanism behind it doesnt make it true. Everything we do is based on instinct. Also plenty of different animals have language. Not speaking language like ourselves but perfectly fine language for themselves. Bees use chemicals and body movement, mammals use sounds and body language, etc. We arent different from any other mammal. Our brains are larger but it pretty much stops there.
