“Kilroy was here,” 15,000 B.C.
Once upon a time, before the Sahara was a desert, people lived there and sometimes painted pictures on the rocks. Sometimes they just spread a hand on the rock and squirted paint around it: probably a kind of signature.
We are occasionally asked to believe that lizards did this, too.

I’ve had a lot of different kinds of lizards as pets, and not a single one of them ever displayed the slightest interest in painting anything.
That is a mystery. In good faith, I’ll accept the notion that these are shaped incorrectly to be human infants. So, someone in ancient Egypt used lizards to create graffiti? Makes more sense than some of the things I hear on the news. 🙂
