Palaeolithic is a really long and confusing word that means old stone age. This is a time a really long time ago when people lived by hunting and gathering food, which means they didn't grow their own food like we do now.
During this time, people didn't have things like technology, cars, or even homes like we have now. They lived in caves or made their own shelters, and they used stones for making tools or weapons.
The Palaeolithic period happened a long, long time ago, way before you, your parents, or even their grandparents were born. So, it is really cool to learn about it and imagine how people lived back then.
