At the time of Jesus’ life in Jerusalem, Flavius Josephus, a Jewish historian, wrote the Antiquities of the Jews. In it he wrote of the effects of the fall of the tower of Babel:
After this they were dispersed abroad, on account of their languages, and went out by colonies everywhere; and each colony took possession of that land which they light upon, and unto which God led them; so that the whole continent was filled with them, both the inland and the maritime countries. There were some also who passed over the sea in ships, and inhabited the islands. And some of those nations do still retain the denominations which were given them by their first founders: but some have lost them also. (Book 1, Chapter 5).
At least this point made in antiquity is consistent with the story of the Jaredite journey.
