Any one read Chapter 4 of Genesis lately?

It shows that Cain and his descendants were smart and intellegent?  Cain's family built cities, they weren't just cave dwellers or hunters and gatherers. 

"Jabel was the father of those who live in tents and raise livestock"

"Jubal was the father of all who play the harp and flute"

""Tubal-Cain who forged all kinds of tools out of bronze and iron"
