Sometime towards the end of 1982..
The earliest people lived in caves. They made lamps with clay and animal fat to heat and light their damp dark homes.
Cave men spent all their time hunting for food. As men became farmers they began to built huts with walls and a roof.
The fire was made of flat stone and the smoke went out through a hole in the roof. Some flat stones covered with skins made a bed. If there was no stones to make a wall they set up a ring of posts and tied poles from them to big post in the middle.
When a group of huts had been built a long fence was put right round them to keep out wild animals and enemies. Inside the fence were houses pens for the animals hayricks and poles for drying grass and dew pond.
To be safe some tribes built their houses in swamps or in lakes. They put a fence all round.
