The "Rock Age," also known as the Stone Age, is a prehistoric period characterized by the use of stone tools and weapons. It is divided into three main phases: the Paleolithic, Mesolithic, and Neolithic. The Paleolithic era, the longest phase, saw early humans as hunter-gatherers, while the Neolithic period marked the advent of agriculture and settled communities. During the Rock Age, humans developed essential skills such as tool-making and fire use. Artifacts from this time, including cave paintings and pottery, provide insight into early human life and culture. The Rock Age laid the foundation for subsequent historical developments in human civilization.
