According to the egyptians the creator of speech was the god Thoth
Babylonians believed that the language giver was the god Nabu, and the Hindus attributed our unique language ability to a female god: Brahma was the creator of the universe ,but his wife Sarasvati gave language to us.
Plato held that at some ancient time, a legislator gave the correct, natural name to everything , and that words echoed the essence of their meanings.
Belief in the divine origin of language is intertwined with the supernatural properties that have been associated with the spoken word. In many religions only special languages may be used in prayers and rituals , such as Latin in the Catholic Church for many century. The Hindu priests of the fifth century B.C.E. believed that the original pronunciation of Vedic Sanskrit was sacred and must be preserved. This led to important linguistic study because their language had already changed greatly since the hymns of the Vedas had been written. The first linguist known to us is Panini , who wrote a descriptive grammar of Sanskrit in the fourth century B.C.E. that revealed the earlier pronunciation , which could then be used in religious worship. Even today Panini's deep insights into the working of language are highly revered by linguists.
Although myths , customs , and superstitions do not tell us very much about language origin , they do tell us about the importance ascribed to language. There is no way to prove or disprove the divine origin of language , just as one cannot argue scientifically for or against the existence of deities.
