It just kills me how, when certain people find an impressive work of craftsmanship or art that appears old they conclude it must be alien.  “I couldn’t have made anything like that, and no one I know could have, either. They must have an extraterrestrial origin!”  Good grief.

Here’s a recent article on the crystal skulls, now immortalized in the title of the new Indiana Jones movie. Sorry, Indy, they weren’t made by ETs.

And yes, I’m going to see the movie.
