Nonono, animals don't have language. Period. They communicate, but it's not language and it isn't possible to communicate complex thoughts. They have an instinctual knowledge of how to communicate, but if you think about it humans do too. What do babies do? They cry. Who taught them to cry? Nobody. The thing is, humans don't need the simplistic and instinctual communications that other animals have because we have language. And language is so much better, because it can get across a vast amount of complex thoughts.
