Prehistoric times refer to the period in human history before written records were kept. This era includes the Stone Age, Bronze Age, and Iron Age, during which early humans developed tools, art, and social structures. People lived as hunter-gatherers, relying on nature for food and shelter, and they created cave paintings, such as those found in Lascaux. During prehistoric times, various species of hominids evolved, leading to the emergence of Homo sapiens. These early humans migrated across continents, adapting to different environments. The discovery of fire and the development of language were significant milestones that shaped human culture and survival.
