Stone Age is the earliest period of human history when people used stone tools. It began about 2.5 million years ago and lasted until around 3000 BCE in many regions. It is divided into different stages.

People made tools from stone, wood, and bone for hunting and daily tasks. Early humans lived as hunter-gatherers and later began farming. Evidence of Stone Age life has been found in Africa, Europe, Asia, and other regions.

The Stone Age includes the Paleolithic, Mesolithic, and Neolithic periods. Each stage shows changes in tools, lifestyle, and settlements.
