Did the scientist who said the himalayas would melt in 2020 date this? Im a simple girl, but bread without havesting and milling (agriculture)is called a miracle.. maybe its manna.
Agriculture is the planting and replanting of the seed, tilling the soil, watering, then harvesting.
Obviously, there were wild grains long before agriculture, and still are. Those were harvested for food.
Most likely the early grains were prepared as bulgar (boiled and mashed) before more advanced milling equipment (i.e. flat rock) was discovered or built.
