There is no universally accepted definition of what a human is -- and in the past, people have been declared nonhuman (subhuman) because of race,
culture, country of origin, gender, sexual preference, physical anomalies (albinos and dwarfs, for instance), wealth, and a host of other trivial
differences that are not genetically based.

Why I'm skeptical about the "Cave of Petroglyphs"
I've studied them for years. "Bas relief" carvings (where the stone is carved/pecked away from the image) is not a technique used in the oldest
style of rock art (It's hard enough to peck a line into a rock, but pounding away large sections of it to produce an elevated figure would take a
very long time.) There is a mix of styles which appear to be copied from other authentic petroglyphs. There are deep sharp edges (and if you got
close enough, you could probably see metal chisel marks rather than pecking marks from stones.)
Some of them appear to be Incan motifs and are eroded badly enough that they look reasonably authentic for that time and style. This MAY be an older
site defaced in modern times.
NOTE ON THE FOLLOWING SITES: They apparently "chalk" the petroglyphs so they will photograph better (this makes rock art preservationists grit
their teeth in annoyance. It's not good for the site and can destroy traces of older pigments (if they were painted) Authentic ones -- Spanish language site
