In early prehistoric times, the hunter-gatherers used to live in the Netherlands. As the name implies, they survived by hunting and by gathering berries, nuts, edible fungi and plants. They had not yet invented pottery and their clothes were made of animal skins or plant materials. Hunter-gatherers had no permanent homes. They were nomads. Wherever they could find drinking water, animals to hunt and plants to gather, they would build a hut. When they had used up all the food in the area, they moved on to a new place and built a new hut. Thousands of years later, archaeologists find almost no traces of these huts in the ground. Because the huts were made of organic material like wood and plants, they usually rot away. So nobody knows exactly what the huts looked like.
