Puzzled Aliens is the 45th puzzle from The Curious Village.
From high in the sky, a pair of aliens observes humans using a bizarre object. Perplexed, one alien turns to the other and says: "How strange. The Earthling is opening a hole in a sheet of paper and marking it with a line to show the other Earthlings where the hole is. I've never seen anything like it!" What could these extraterrestrial visitors be talking about?
