Synopsis: Extracted from BBC: "Huygens questions why God would have created other planets 'just to be looked' upon from Earth. He concludes that aliens must have hands and feet like humans because of their "convenience", writing: 'What could we invent or imagine that could be so exactly accommodated to all the design'd uses as the Hands are? Shall we give them an Elephant's Proboscis.' He also suggests that "celestial beings" must have feet '[unless] they have found out the art of flying in some of those Worlds'. The writer believed aliens enjoyed astronomy and observation, sailed boats and listened to music but also suffered misfortunes, wars, afflictions and poverty 'because that's what leads us to invention and progress'. The author ruled out the possibility of much larger animals than those currently existing on Earth because it was written before humans knew about dinosaurs."
