Serious people have speculated for eons about the possibility of life and intelligence in not-Earth. Democritus (Greece, 460 BCE-370 BCE) said with amazing foresight: “In some worlds there is no Sun and Moon, in others they are larger than in our world, and in others more numerous. In some parts there are more worlds, in others fewer (…); in some parts they are arising, in others falling. There are some worlds devoid of living creatures or plants or any moisture.”
