I love to imagine this kind of thing dug up by an alien civilization. That it displays the moons of Jupiter will be a fun puzzle and a source of wonder. “Obviously”, they will say, “these people must have worshipped Jupiter as a god and used the position of its moons to keep time.” But the pieces of the puzzle will never quite fit.
Who knows, maybe the Antikythera mechanism or the pyramids were a similarly ludicrous prank?
