Why do we look at ancient artifacts and assume there's one reason they were made? We don't look at a museum full of paintings and assume there's one reason they were painted. We're intelligent enough to know that each artist paints for his own reasons. Why can't we afford that same recognition of artistic individuality to ancient artists?

Why did primitive men use little rocks to peck holes into bigger rocks? There are probably as many answers as there were people doing the pecking. Some undoubtedly did it as a way to record observations about their surroundings*. Some may have done it for spiritual or magical reasons. Others may have done it from sheer boredom or simply because everybody else in the 'hood was doing it. They may have even had races to see who could peck the most holes in an afternoon. Whatever possible motive you can dream up, there was probably some person or group of people who did it for that reason.


*And the night sky was a HUGE part of primitive man's surroundings. We tend to marvel at ancient people's knowledge of things astronomical. Well, you'd know a lot about the night sky too if it were ALL you had to look at after the sun went down.
