Wisdom from Cain

20 And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle.
21 And his brother's name was Jubal: he was the father of all such as handle the harp and organ.
22 And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah.

Amazing that the organ was invented in ~3500 BC...Why does it seem a lot of wisdom is in Cain's line?

Cain line ends in the bible with Jabal, Jubal, Tubal-cain, Naamah so we don't know the rest of the wisdom of the line .
