Culture and its Influence on the Development of Language

What was the first spoken word, or what was the first thought of communication? These are my thoughts and the premise that communications, "words", are based on environment and other influences. My thoughts are that people and the form of words were and are developed by outside influences and by these outside influences come the development of cultures and societies. Words are and can be the basic foundation in building and losing these cultures and societies. We have seen the languages of cultures are lost every day and that even in today's societies new words are formed. We as a people should reflect about the beginning of our first words and how we communicate. These are my views on the basic development of communication.
