Records of human life was not recorded millions of years ago. The Prehistoric Period dates from 2.5 million years ago to 1,200 B.C. It is categorized in three archaeological periods: the Stone Age, Bronze Age and Iron Age. In the stone age, humans lived in caves or simple huts or tepees and were hunters and gatherers.They used basic stone and bone tools, as well as crude stone axes, for hunting birds and wild animals. They cooked their prey, including woolly mammoths, deer and bison, using controlled fire. They also fished and collected berries, fruit and nuts. They used combinations of minerals, ochres, burnt bone meal and charcoal mixed into water, blood, animal fats and tree saps to etch humans, animals and signs. They also carved small figurines from stones, clay, bones and antlers. During the Bronze Age. Bronze, copper and tin alloy, was discovered. Used for weapons and tools, the harder metal replaced its stone weapons and tools, it helped spark innovations including the ox-drawn plow and the wheel. The invention of the potterâs wheel, and textilesâclothing consisted of mostly wool items such as skirts, kilts, tunics and cloaks. Homes morphed to so-called roundhouses, consisting of a circular stone wall with turf roof, complete with a fireplace or hearth, and more villages and cities began to form. Law and warfare, as well as beginnings of religion, also came into play during the Bronze Age, perhaps most notably relating to the ancient Egyptians who built the pyramids during this time. The discovery of ways to heat and forge iron kicked off the Iron Age (roughly 1,300 B.C. to 900 B.C.). At the time, the metal was seen as more precious than gold, and wrought iron (which would be replaced by steel with the advent of smelting iron) was easier to manufacture than bronze. Mass production of steel tools and weapons, the age saw even further advances in architecture, with four-room homes, some complete with stables for animals, joining more rudimentary hill forts, as well as royal palaces, temples and other religious structures. Early city planning also took place, with blocks of homes being erected along paved or cobblestone streets and water systems put into place. Agriculture, art and religion all became more sophisticated, and writing systems and written documentation, including alphabets, began to emerge, ushering in the Early Historical Period.
