Prehistoric Britain refers to the time before written records, spanning from around 800,000 years ago to about 43 AD. During this period, early humans, such as the Neanderthals and later Homo sapiens, inhabited the land. They lived as hunter-gatherers, using tools made from stone and bone, and left behind evidence of their existence through artifacts and cave paintings. The landscape of prehistoric Britain was diverse, featuring forests, rivers, and open plains. Significant sites like Stonehenge and Avebury were constructed during the Neolithic period, showcasing the advanced social organization and spiritual beliefs of these early communities.
