Source - How was Language Originated?Because languages leave behind no fossils, it is difficult to put our finger on the exact time when human language originated. Some scientists dubiously attempt to guess the sophistication of primate communication based on the complexity of the tool industry at the time. We may never know for sure when language originated, until we are able to use preserved DNA from ancient homonids to recreate them and observe their language capacities.
Rather than evolving abruptly, it is likely that language as we know it developed over a long period of time. Some scholars believe that the advent of bipedalism 3.5 million years ago brought anatomical changes, such as a more L-shaped vocal tract, which would have expanded the range of possible sounds. Whether primates at this time actually used this anatomy to make more sophisticated sounds is not known. These "missing links" are now all extinct.
Research of homonid skulls has found that about 400,000 years ago, Neanderthals had a hypoglossal canal similar in size to that of modern humans. The hypoglossal canal is a bony channel that routes nerve fibers associated with the production of speech, although some studies have found an inconclusive link between the size of this canal and speech capabilities. Neanderthals possessed a tool industry significantly more sophisticated than earlier homonids, and had large brains. Many scholars suspect that Neanderthals had some rudimentary form of language, and tentatively believe that modern language originated around 400,000 years ago.
Although the precise time when language originated remains unknown, it was certainly in use 200,000 years ago, when modern humans evolved in Africa. These humans were modern anatomically, but behaved similarly to some of the simpler homonids that came before them until about 100,000 years ago. About 50,000 years go, a small group of humans left Africa. Some scholars argue that this departure signifies that humans had reached some threshold level in their capacity to communicate, which made them capable of leaving, although this hypothesis is quite doubtful.
Most scientists believe that all modern language originates from a single source, rather than having developed independently on all continents. If so, it must have come from a source at least as far back as the common ancestor of all living humans. All modern humans are ancestors of "Mitochondrial Eve," a female that lived in Africa approximately 150,000 years ago. Modern language may date back to this era, or may be more recent. About 70,000 years ago, the human species experienced a severe population bottleneck when the total number of individuals may have been as low as 2,000. The global language might also date back to this period.
Language has no known origins.
Language is assumed to have originated from a single source.
Language today is acquired both at young and old ages alike. The common element in language acquisition is a teacher. Whether a personal teacher face to face or a digital teacher on electronic media or a mute teacher in text. Someone is responsible for every word one learns.
People are capable of making up words and codes. One can call anything by any name of one's choosing. Yet what we find is a dependence on an original language to formulate a new one. For if a new language is formulated independent of all other languages no one will understand the creator except the creator. This is the very basis for secret code languages. Their ultimate downfall is they must be translated back to a known language, thus an opening for spies to gather intelligence. Thereby making every secret form of communication vulnerable to eavesdropping.
Note ancient languages are complex, and in some circumstances even more complex than the languages we use today. Complexity is based on the grammatical structure of the language, the vastness of the alphabet, and the vastness of the vocabulary available.
Although vocabulary of languages grow with time with the advent of new concepts, the grammatical structure of ancient languages can be far more complicated than modern languages.
So who taught the first language? The scientific response, although uncertain, attempts to attribute this to the first humans themselves. The claim revolves around the ability to produce sound indicative of sounds for languages known today. But is ability enough?
Note the interesting presence of feral children:
What many feral children do learn is to mimic animal sounds, and especially the sounds of their host families. Those that have lived with wolves are often reported as barking or whining, and those that have lived wild on their own are sometimes adept at recognising and imitating the sounds of many different birds. In the Optomen Television production Feral Children, Oxana Malaya can be seen running around on all fours and barking like a dog.
Note - Victor lived till he was 40 and was found when he was 12.It seems that Victor of Aveyron was eventually able to respond to some spoken commands, although to what extent he was genuinely understanding the language we don't know. He never spoke. Wild Peter made a few distinct noises himself, of which the two most recognisable were "ki scho" and "qui ca", for King George and Queen Caroline.

It appears the human race is a race of imitators. What then were we imitating when we adopted the worlds various languages? What in nature produces such sounds? Nothing that I have ever heard...
So where is the origin? Where is the one we all so happily imitate?
In both the Bible and Qur'an this original origin of imitation is God.
Language itself is evidence of God.
Now please be aware that evidence of God is not evidence of God's attributes. It is not evidence of a specific religion. It is not evidence of any one Scripture.
So bringing up points that God might be an alien is irrelevant. Whatever you personally want to consider this being is irrelevant to evidence for this being's existence. If one is one comfortable thinking God is an alien, the universe itself, or a personal being with a specific set of attributes, that is fine. But it is not the core of the discussion here.
