Adam in the garden started with the task of naming all the animals. (Gen 2:20) But God also spoke to Adam immediately (Gen 1:28-29) and Eve misquoted Him to the serpent. From a literal interpretation, it would appear that God created language, language immediately began to evolve (Adam added animal names), God scrambled it at Babbel, and we have passed down our scrambled, evolving versions ever since. There are new words and terms being created daily. We've even seen a few right here on this board.
Interesting topic.
Linguistics is an interesting field of study.
How about the Bible in someones language who does not have a written or spoken language? Its called structural linguistics. Some Missionary organizations train people to do it and send them out. I think that is totally awesome.
We have a dear friend who is an evangelist whose first language is sign. He is hearing but both parents were deaf.
I once read of a group of children who were all deaf, I don't remember what country they were in, and someone went to teach them American sign language. They did not learn it, but made up their own sign language.
