Genesis 10

These are the generations of the sons of Noah, Shem, Ham, and Japheth. Sons were born to them after the flood.

The sons of Japheth: Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras. The sons of Gomer: Ashkenaz, Riphath, and Togarmah. The sons of Javan: Elishah, Tarshish, Kittim, and Dodanim. From these the coastland peoples spread in their lands, each with his own language, by their clans, in their nations.

The sons of Ham: Cush, Egypt, Put, and Canaan. The sons of Cush: Seba, Havilah, Sabtah, Raamah, and Sabteca. The sons of Raamah: Sheba and Dedan. Cush fathered Nimrod; he was the first on earth to be a mighty man. He was a mighty hunter before the Lord. Therefore it is said, “Like Nimrod a mighty hunter before the Lord.” The beginning of his kingdom was Babel, Erech, Accad, and Calneh, in the land of Shinar. From that land he went into Assyria and built Nineveh, Rehoboth-Ir, Calah, and Resen between Nineveh and Calah; that is the great city. Egypt fathered Ludim, Anamim, Lehabim, Naphtuhim, Pathrusim, Casluhim (from whom the Philistines came), and Caphtorim.

Canaan fathered Sidon his firstborn and Heth, and the Jebusites, the Amorites, the Girgashites, the Hivites, the Arkites, the Sinites, the Arvadites, the Zemarites, and the Hamathites. Afterward the clans of the Canaanites dispersed. And the territory of the Canaanites extended from Sidon in the direction of Gerar as far as Gaza, and in the direction of Sodom, Gomorrah, Admah, and Zeboiim, as far as Lasha. These are the sons of Ham, by their clans, their languages, their lands, and their nations.

To Shem also, the father of all the children of Eber, the elder brother of Japheth, children were born. The sons of Shem: Elam, Asshur, Arpachshad, Lud, and Aram. The sons of Aram: Uz, Hul, Gether, and Mash. Arpachshad fathered Shelah; and Shelah fathered Eber. To Eber were born two sons: the name of the one was Peleg, for in his days the earth was divided, and his brother's name was Joktan. Joktan fathered Almodad, Sheleph, Hazarmaveth, Jerah, Hadoram, Uzal, Diklah, Obal, Abimael, Sheba, Ophir, Havilah, and Jobab; all these were the sons of Joktan. The territory in which they lived extended from Mesha in the direction of Sephar to the hill country of the east. These are the sons of Shem, by their clans, their languages, their lands, and their nations.

These are the clans of the sons of Noah, according to their genealogies, in their nations, and from these the nations spread abroad on the earth after the flood.

Genesis 11:1-9

Now the whole earth had one language and the same words. And as people migrated from the east, they found a plain in the land of Shinar and settled there. And they said to one another, “Come, let us make bricks, and burn them thoroughly.” And they had brick for stone, and bitumen for mortar. Then they said, “Come, let us build ourselves a city and a tower with its top in the heavens, and let us make a name for ourselves, lest we be dispersed over the face of the whole earth.” And the Lord came down to see the city and the tower, which the children of man had built. And the Lord said, “Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them. Come, let us go down and there confuse their language, so that they may not understand one another's speech.” So the Lord dispersed them from there over the face of all the earth, and they left off building the city. Therefore its name was called Babel, because there the Lord confused the language of all the earth. And from there the Lord dispersed them over the face of all the earth.

Answer:  What kind of name lasts forever?

Question: Only the one God gives in Christ. Every human attempt to build identity fades, but those who receive His Name share His life forever.

Philippians 2:9–11
“Therefore God has highly exalted Him and bestowed on Him the name that is above every name, so that at the name of Jesus every knee should bow…and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.”
