The formative period for civilized humanity on Old Earth, from about 7000 BT (5000 b.c.e.), when societies transformed by agricultural technologies became common to about 270 BT (1700 c.e.) when the first societies transformed by Industrial technologies arose and brought about the Industrial Age. Agricultural technologies permitted humans to harness a significant fraction of the biosphere's output through the use of domesticated animal and plant species. The resulting energy subsidy supported unprecedented population densities and societal complexity. Cities, written records, organized religions, monetary systems, formal governments, armies, bureaucracies, and the other trappings of civilization were the result. These led in turn to the discovery of the more potent energy sources that permitted the Industrial Age. Subdivisions of the Agricultural Age are sometimes named for notable technologies of the period (Iron Age, Bronze Age, Neolithic). The term 'Agricultural Age' may also be used for the characteristic technologies of this period, or for Terragen civilizations that by choice or chance are at a comparable level of development, or for similar periods in the development of xenosophont civilizations.

Agricultural Age - Text by Stephen Inniss The formative period for civilized humanity on Old Earth, from about 7000 BT (4000 b.c.e.), when the first societies transformed by agricultural technologies appeared, to about 270 BT (1700 b.c.e.) when the first societies transformed by Industrial technologies arose, bringing about the Industrial Age.
