No places to live

Long-long time ago people didn’t have houses. They slept under trees or in caves, under rocks.

There were no supermarkets and ATMs, there was no money. They didn’t have buses or cars, or horses. People walked around and found fruits, nuts and vegetables to eat. They just walked, all day, looking for food. There were no countries, so they didn’t need passports. They went wherever they found food.

• Why did they sleep in trees?
• Is it easy to find nuts?
