Where Did Language Come From?

A number of years ago I took 6 credit hours of classwork at WSU that dealt with languages and how they are put together. These linguistical studies were in preparation of studying the Czech language when we went on mission to that country. 
Our professor just happened to be a Christian and was in fact an elder at Central Christian Church. There was lots of information that reinforced the knowledge language was given to us by God. The human mind is so constructed that beginning in infancy the child’s brain is specifically constructed to learn language. That ability to learn a second third or fourth language without accent remains until about the age of 10 to 12 years of age. After that the synapses of the brain are modified and can no longer learn language as it once did. 
Interestingly, languages of every kind are becoming simpler in their structure. If evolution were true, then languages should be becoming more complex. After all, evolutionists claim that languages developed according to that paradigm. English is simpler now than when the KJV Bible was translated. No longer do we find verb endings distinguishing past or present tense. Verb endings that we see in the King James Bible are gone. All languages experience this phenomenon of simplification
Evolutionists are completely confused as to how language even developed in their presupposition that it developed naturally. Here are some of their current theories:
1. The Bow-wow theory. The idea that we imitate sounds made by objects. But few of our words are used for this purpose.
2. Pooh-pooh. Words develop from sounds for surprise, pain, elation, etc. Yet, animals make similar sounds without developing language.
3. Ding-dong. Speech reflects a “mystical resonance with the world”. Even evolutionists think this unlikely.
4. Yo-he-ho. Speech developing from rhythmic chants used as people work together. If I were an evolutionist, this might show most promise, but most language is not for this purpose.
5. Ta-ta. Sounds to go with gestures, like waving goodbye. But where did the gestures come from?
6. La-la. Sounds from music or poetry. But language would seem to be necessary before such artwork. 
We see how none of these theories could possibly develop into the complex languages we understand and see about us. The God of heaven gave us language so we could communicate as a society.
