This is posted under "movies" do you want to know what language a certain movie about adam and eve was produced in ? If so you need to be more specific about what movie you are talking about.

We know from modern day revelation that God taught Adam, and that he kept a book of remembrance. The language was called the "Adamic" language, and was continued to be used until God confounded and scrambled the languages at the tower of Babel.
