Prehistoric humans are the early ancestors of modern humans who lived before written records. They existed during the Stone Age, Bronze Age, and Iron Age, using simple tools made from stone, wood, and bone. These early people were primarily hunter-gatherers, relying on hunting animals and foraging for plants for food. Over time, prehistoric humans developed more complex societies. They began to create art, as seen in cave paintings, and formed early communities. The discovery of agriculture marked a significant change, allowing them to settle in one place and develop farming techniques, which led to the rise of civilizations.
