There are several reasons. First, much evidence of prehistoric1 civilization is found in caves because the natural shelter helps preserve artifacts. The earliest cave dwellers2 date to the Paleolithic period, around 2.5 million years ago, and evidence suggests that these ancient nomads3 used caves as temporary shelters during their seasonal4 wanderings. The caves often lay on valley slopes and provided excellent views of animal migration5 routes. But there is no evidence that Stone Age peoples set up shop in caves for very long. Even Neanderthals, who lived in relatively6 cold regions of ancient Europe, used caves only for temporary shelter. Our more immediate7 ancestors did, of course, eventually move indoors. But permanent dwellings8 came about only with the invention of agriculture and animal husbandry. Before those world-changing inventions, prehistoric people were forced to follow their food away from the warmth and shelter of the cave.
