8,000 years ago

Our World Heritage: 8,000 years ago, the ice sheet had melted over Finland and Sweden with the exception of a few glaciers. The oldest traces of people in the High Coast have been found from a ledge on the mountain Skuleberget. The ledge is today at 160 metres above sea level which makes the findings about 8,500 years old. It was probably the seal hunters who used the cave as a temporary camp. 

Other World Heritages: Tehuacán-Cuicatlán Valley is a World Heritage Site in Mexico. 7,800 years ago the indigenous people living in the valley were the first humans to grow corn and beans and build irrigation systems.
