Aliens, Us, and Chimpanzees

If an alien race visits the earth, I don't think they will differentiate much between us and our keen chimpanzees. We are not that different! What they will report to their home planet is that among all the other animals on this planet, they have found one species that is a tool maker and has managed to build pretty advanced tools. This animal tends to be social and gathers in large groups, but apart from that is not much different from other members of its branch, the primates. It is conniving, predatory, vicious, selfish, greedy. It tends to spend most of its time fighting other members of its species over resources and is very brutal towards any living thing, including its own kind.
