What you believe was the most important aspect relating to the spear of language

I think the most important aspect relating to the spread of language is that we could communicate better and tell each other what we needed in a timely manner. Proof of this is day to day life we communicate to one other everyday from asking for food to getting a job. Without the spread of language it would be close to nearly impossible to have a civilized society or to ever get anything accomplished. It even helps us in relationships like communicating in relationships with family, friends, teachers, society. We use it in modern day technology (e-mail, standard mail, text/phone calls).
