The difference between animals and humans.

Animals mostly move by instinct. We also have instincts, but we can control them much better. We are mainly guided by reason. Animals set more instincts in motion and only use some reasoning.
People have a complex language and method of communication. People can speak, write, read facial expressions, gestures, and more. Some may even speak multiple languages. Animals communicate, but they cannot communicate at the human level.
People use their brains in much more sophisticated ways. The cognitive abilities of humans are incredible compared to animals.
