When primitive man came to know grain he valued it greatly because it could be kept even during winter, when food was usually scarce. But those little hard grains were no good to young children or to old people without teeth. Some mother, perhaps, thought she would try and mash them up into softer form to give to her baby. In this way she produced a rough sort of flour and discovered how to grind flour from grain.
The woman used barley or wheat flour to make small pancakes which they dried in the sun. They then learned how to place which they dried in the sun. They then learned how to place pancakes on top of hot stones or in the embers of a fire. They discovered that the dough was much nicer to eat when it had been toasted and this was how bread was born. The men who went hunting by now were taking along these rough pieces of bread with them.
The first good pictures of primitive baking come from the tombs of the ancient Egyptians. They show all stages of bread-making, from the removal of grain from the granary, the grinding on stones and subsequent sifting, to the mixing and kneading of the dough and the baking of the bread in large pots.
Man also learned to till the soil better: he sowed wheat and cultivated it carefully. Later man learned to prepare the soil with a plough pulled by animals instead of scratching it with a stick, and so the grain grew even better.
