Answer:
True
Explanation:
The Tsodilo Hills are mountains emerging from nowhere in the middle of the Kalahari Desert in northern Botswana. They are considered sacred by Aboriginal Bushmen. Their ancestors created here one of the largest rock art sanctuaries in Africa. The cave paintings are between 3,000 and 4,000 years old and the presence of penguins and whales confirm that the ancestors of today's Bushmen were also nomads and reached the Namibian coast.
