💪✍Great Analysis on how God's division/seperation of Noah's grandsons and grandsons' sons and their descendants is where the 70 ethno-nations that both existed back then AND still exist today do come from:

Total amount of biblical nations:
12 ethnonations of/from Iaphet
+ 26 ethnonations of/from Ham
+ 22 ethnonations of/from Shem
= 70 TOTAL ETHNONATIONS
(Genesis 10:1-32)

✍Details on Ham's sons
-Cush had 6 sons: Seba, Hauilah, Sabtah, Raamah [who had 2 sons named Sheba and Dedan], Sabtecha, and Nimrod [who is 1 of Cush's sons & founded both the kingdom of Babel & multiple cities as per Genesis 10:8-10, Asshur of Genesis 10:10-12 is of/from Cush's son Nimrod's kingdom/land so he/Asshur was not included in the total count of Noah's sons & grandsons & their nations.]
-Mizraim had 7 sons [which became 8 nations due to Mizraim's son of his son/ Mizraim's Casluhim's son Philistiim & descendants becoming a seperate nation from Casluhim and leaving the land of Caphtor]: Ludim, Anamim, Lehabim, Naphtuhim, Pathrusim, Casluhim "(out of whome came Philistiim)" [the 1 nation of Philistiim came out of the 1 nation of Casluhim - see also Amos 9:7, Genesis 10:14, & Zephaniah 2:5 on the Philistines], and Caphtorim.
