Human beings are the only intelligent life in the universe?
From a long time before, human beings are believed to be the only intelligent life in the universe.
As a evidence, we can communicate by speaking and listening and can appear emotion. We all may understand this. However, human beings are the only outstanding creature in the world and there might be more animals that are intelligent such as apes. They live in a group. Then, they have to communicate each other. I think that they cannot live unless they understand each other. Therefore, there are more intelligent life in the universe. Recently, a study about animal intelligence soluve other animals. I am looking forward to seeing the study.
