"They live in the vastness of the Kalahari in small family groups. One family of Bushmen might meet up with another family once in a few years. But for the most part, they live in complete isolation quite unaware there are other people in the world. In the deep Kalahari, there are Bushmen who have not seen or heard of civilized man. Sometimes they hear a thundering sound when there are no clouds in the sky. And they assume the gods have eaten too much and their tummies are rumbling up there. Sometimes they can even see the evidence of the gods' flatulence."
