The site you listed shows that during a colder time the sons of God (prehistoric people) gathered WILD grains. These people were NOT stupid but were as intelligent as mindless Nature could make them. They had "evolved" their lifestyle over some 6 Million years AFTER they had diverged from Chimps. They were NOT Human until after they married Humans (descendants of Adam) and INHERITED Adam's superior intelligence which is like God's. Gen 3:22
*** Oldest city 4,500 BCE, or 6,500 years ago. That is 16,5000 years after agriculture:
The Ancient City
The city is the first LARGE city which was not the first small city.
*** Those are the two that you mentioned. What other human traits would you like to be corrected on?
Gathering seeds to eat during a cold period was practiced by every hungry animal and was NOT like the Human farming, Adam practiced. To find other Human Traits on Adam's Earth BEFORE the Ark arrived on our Earth read Gen 4:17-22 to see that Cain's descendants had tents, musical instruments and smelting of brass and iron, thousands of years BEFORE Noah arrived on our Planet.
