Asia
The coastal periphery was home to some of the world's earliest known civilizations, each of them developing around fertile river valleys. The civilizations in Mesopotamia, the Indus Valley and the Yellow River shared many similarities. These civilizations may well have exchanged technologies and ideas such as mathematics and the wheel. Other innovations, such as writing, seem to have been developed individually in each area. Cities, states and empires developed in these lowlands.
Stilbaai
Another archaeological site is situated in a group of caves at Blombos cave, about 12 kilometres from Stilbaai. Artifacts found at Blombos have been carbon dated to around 77,000 BP, making it the oldest known human settlement today.
