Genesis 10:32
“These are the families of the sons of Noah, according to their genealogies, by their nations; and out of these, the nations were separated on the earth after the flood.”
There is no doubt among those who trust in Scripture that “out of these,” the three sons of Noah named Shem and Japheth and Ham, the whole world as we know it, “was separated (into nations) on the earth after the flood.” From these three, the whole earth was populated (Genesis 9:18-19)
Therefore, the whole earth was of one family, one language, one speech, one race (Genesis 11:1). This, even heathen writers acknowledge; and that language was probably Hebrew.
Shalom my brothers and sisters.
