The Tower of Babel narrative is the Yahwistic (in reference to the Yahwist document posited by the Documentary Hypothesis) tradition's explanation of why different languages exist. The Priestly tradition, on the other hand, explains this during the Table of Nations narrative, with the line 'These are the sons of Shem, after their families, after their tongues, in their lands, after their nations.' (Genesis 10:31).
It's also the Yahwistic tradition that talks about Adam and Eve in the Garden of Eden, and Yahweh's fear that if they eat from the Tree of Life, they will become like on of the gods.
