The Stone Age was a time thousands of years ago, when early humans lived in caves and jungles.Life was simple, and there were only two main things to do.To protect themselves from the wild animals and to gather food.
For both purposes, people made tools from stone.The oldest stone tool that we have as an evidence is almost 3.4 million years old.It was found in Lower Awash Valley in Ethiopia.The Stone Age ended somewhere in between 6000 BC to 2500 BC.Around that time stone tools were replaced for copper tools.Stones were also used to make fire. And since in those times humans used stone for almost everything they did, we call it The stone age.
In the early years of the Stone Age, humans used stones besides wood and bone tools for chopping tasks (these were the choppers). Later, they learnt to develop a special kind of sharp stone called flint which was used to cut and chip things quickly.As the humans became smarter they started to make even more complex tools than before. The flints were probably used as barbs on arrows, spears and other composite tools.
The Stone Age people just ate animals and plants.They wrapped themselves in animal fur and sat around fire to keep warm. Stone Age people could communicate with written symbols. All their words and ideas were expressed in symbols. They were talented artists.
