Answer:
It plays an important role in our life, because language can help us communicate to other people. The people who we would like to know but we can't communicate because we don't know the said language. Language is like a connectors for people who wanted to communicate with other people. If we say that we don't need language, but how can we understand each other without the language we spoke or the language were using right now. It's feels like some force are stopping us from understanding each other. For example when you meet a foreigner but can't understand it's said language, it's like there's a barrier that is stopping us from communicating with each other. I could say that language is like a part with us, a part that would play a role as a communicator.
[Creator's Note: You could take my answer as a reference, I myself saw language this way but I'm also not sure if that's really the answer. And I'll say this again, this answer is not really the specific answer that I think would connect for the discussion you are in but the answer was actually just an opinion and it's not an answer key like you would expect or something but hopefully this idea/opinion helped you]
