That was a cool documentary. That engineer dude who recreated it is a genius.
I'm sure there are tons of other inventions and pieces of ancient technology that we'll never discover. Part of me likes to think a modern civilization existed way before the Sumerians but no trace has been left behind. Anthropologists are working with a tiny fraction of evidence and information. If a meteor hit or Yellowstone erupted, evidence of our civilization would probably disappear after a few thousand years.
