74:2.2

The tongue of Eden was an Andonic dialect as spoken by Amadon. Van and Amadon had markedly improved this language by creating a new alphabet of twenty-four letters, and they had hoped to see it become the tongue of Urantia as the Edenic culture would spread throughout the world. Adam and Eve had fully mastered this human dialect before they departed from Jerusem so that this son of Andon heard the exalted ruler of his world address him in his own tongue.
