Origin of all languages

I think sanskrit.

There's a few contenders, although Sanskrit would have to be at the very least one of the original Indo-European language group. Possible earliest languages include the Semitic languages, Sanskrit, early Chinese, Australian Aboriginal, and the original African dialects. The American language groups are believed to have come from Asia, but some of the Native American languages are so different it must have been a pretty lengthy and involved process. The origins of some languages are quite obscure. Magyar, the Hungarian language, sounds Slavic, but apparently isn't. According to one study, Magyar doesn't belong to any other language group. Modern languages and their predecessors are comparatively complex, and well organized grammatically. All of them would have had to be formed from much older languages. In some older languages, using the plural actually involves repeating the noun. It's likely that the modern languages were also severely affected by the waves of migration around the world, similar to the hybridization of English from Celtic, Latin, Saxon, Angle, and Norman languages. Old English sounded nothing like modern English, which is much closer to old Saxon. One of the more difficult points is that most languages start as local dialects. One dialect becomes dominant, and as it evolves becomes a language in its own right. Chinese, with its many dialects, is a case in point. They are generally related languages, but they're now so different that the Chinese have to learn them, and they've lived in the same region for thousands of years.They've also been at least well enough acquainted with each other to trade and fight wars for generations, like the Warring States period. Good example of insular societies developing independently, too. Sanskrit is probably one of the few languages not submerged by foreign languages. A very important heritage. Whatever the original human language, we can rest assured that someone thought they had something to say, and things got a bit out of hand afterwards...

I think our environment creates the need for words and we use them to communicate needs
