Archeological and DNA evidence places the origin of humanity and human culture at 50,000–150,000 years ago. Later archeological and DNA evidence places the Neolithic Revolution—the origin of human civilization and the first evidence for villages, towns, specialized agriculture, the manufacturing of household goods, and trade—in the Persian Gulf region and Mesopotamia about 12,000 years ago. The biblical accounts of the Garden of Eden and Noah’s flood imply that humans were living in the Persian Gulf region during much of the last ice age. Antarctic and Greenland ice cores establish that the last ice age persisted from 12,000 to 120,000 years ago.
A continuing source of challenges to the Bible’s credibility and authority is the claim in Genesis 4 that the first humans were engaging in agriculture and soon thereafter even in metallurgy. Skeptics point out the complete lack of archeological evidence that humans previous to the Neolithic Revolution participated in any kind of agriculture or metalwork.
A response to this argument is that humans everywhere appear to be innately inventive. To say that humans would refrain from any kind of agriculture or metallurgy for tens of thousands of years seems counter to the characteristics of humans.
Recently, a research team offered a reason for the lack of farming evidence prior to the Neolithic Revolution. They cited studies that the climate from 12,000 to 120,000 years ago varied so radically as to render the launch of extensive cultivation and global civilization impossible (see figures 1 and 2).1 The research team concluded that the “last glacial climates were extremely hostile to agriculture.”2

While hostile to extensive specialized cultivation, the radical temperature fluctuations before the Neolithic Revolution might have permitted small mixed farms. For example, a family could plant a dozen different food plants on a two-acre farm with the hope that perhaps half of them might be harvestable. Based on which food crops produce and which do not, the family could move from place to place so as to optimize crop production in response to climate change. A member of that family might have set up a temporary forge occasionally to make one or two metal farming tools.
Nomadic small-scale mixed farming of this kind is highly unlikely to leave behind any discoverable evidence. However, a research team in Israel has actually found such evidence. The team demonstrated that humans living along the shore of the Sea of Galilee 23,000 years ago were cultivating wild cereals.
The team’s demonstration was based on the discovery of “proto-weeds” mixed in with seeds of wild emmer, barley, and oat. The team cited numerous research studies that establish that certain weeds rapidly evolve in response to cultivation. The discovered proto-weeds showed the first signs of such evolution. The team concluded that the presence of the proto-weeds “indicates the earliest, small-scale attempt to cultivate wild cereals seen in the archeological record.”3
Given how rapidly the climate was fluctuating 23,000 years ago (see figure 2), this cultivation evidence shows that the earliest humans were no less inventive and industrious than we are. What held them back was climate instability, not a lack of motivation or intellect.

The team’s discovery also answers the skeptics’ challenge to the credibility of claims in Genesis 4 about the technological achievements of the earliest humans. We now have evidence sustaining the compatibility of biblical and archeological data on the civilization achievements of early humans.
