And unto Eber were born two sons: the name of one was Peleg; for in his days was the earth divided; and his brother’s name was Joktan. (Gen 10:25 KJV)
I think that when Moses wrote, “in his days was the earth divided,” he was referring to the division of languages and nations at the Tower of Babel, but others believe he was talking about the Continental Drift. Here is a humble presentation of why I’m right and they’re wrong.
The word, “Hebrew,” comes from “Eber,” who was Peleg’s father. In fact, the Hebrew language might be more literally called the “Eberite” language. Since Eber is the namesake for the Hebrew nation, he was probably the patriarch at the time of Babel. This lines up perfectly if the Tower of Babel incident happened in the days of Peleg, since he was Eber’s son. The original Hebrew audience would have understood that they were named after Eber, so when they read Gen 10:25, they would have associated Eber’s son with the Tower unless Moses indicated otherwise.
