The Paleolithic Age, also known as the Old Stone Age, lasted from around 30,000 BC to 10,000 BC. Early humans during this time relied on hunting and gathering plants for survival. They lived short lives of 20-25 years on average and communicated through sounds, gestures, and signals. Early humans resided in huts, caves, or tepees and used stone tools for hunting as well as animal skins and jewelry. They believed in spirits and created cave paintings depicting animals.
