Genesis 10 clearly casts the human inhabitants of those nations as owing their existence to Yahweh, as they descended from Noah’s sons and, therefore, Noah—all the way back to Adam, Yahweh’s first human son. The Nephilim bloodlines had a different pedigree. They were produced by other divine beings. They did not belong to Yahweh, and he therefore had no interest in claiming them. Coexistence was not possible with the spawn of other gods.
