How language impact life?

We can't communicate with each other if we don't have a language. We don't have our own identity if we don't have language. You can't ask this question if we don't have language. Therefore, life cannot interact with other life if we don't have language. There will be no exchanging of ideas and no portals to other people. Ideas might also not exist if there will be no language.

Note: We can't understand body languages/sign languages if we don't have a verbal language for verbal language are the one who can give meaning to body languages/sign languages.
