Cool. I'm sure it was carved by aliens because ancient people weren't smart and didn't know how to do anything. That's the kind of message that I feel we often get from folks studying past civilizations and accomplishments of humans in the past. It seems like there are enough accomplishments left from past civilizations that we haven't been able to figure out that maybe it would be universally accepted that past civilizations/men may have known a thing or two.
