Earthling


Earthling, a term identifying inhabitants of the planet Earth, is commonly used in science fiction to contrast Earth-born organisms and characters, whose ethnicity or nationality diaspora originated on Earth, with extraterrestrials. Similar terms are Terran and Gaian.

Historically, the term "earthling" referred to a mortal inhabitant of the Earth as opposed to spiritual or divine entities. In Early Modern English, the word was used with the intention of contrasting "earth" with "heaven", and so presenting man as an inhabitant of the sublunary sphere, as opposed to heavenly creatures or deities. The derivation from the noun by means of the suffix is already seen in Old English eyrþling, in the meaning "ploughman". The sense of "inhabitant of earth" is first attested in 1593. Its use in science fiction dates to 1949, in Red Planet by Robert A. Heinlein.

The word "Human" has the same imposed meaning, since it originates from a PIE word "earthling" < "earth". Compare Latin "human" and "earth, soil".

Its modern use in science fiction literature contrasts "Earth" (the planet) with outer space or hypothetical other planets with sapient life. The term was often used in 1950s science fiction film and novels by aliens to express a disdainful or patronizing tone towards creatures from Earth. The meaning "creature from planet Earth" in the context of space travel may be extended to non-human species, as in "Russia fetes dog Laika, first earthling in space".

The literary effect aimed for is a distancing effect, inviting the readers to contemplate their own species as it might be seen from an external point of view. There is also a belittling effect, in parallel with the use of the -ling suffix in such diminutives as "duckling" and "gosling". Especially in 1950s science fiction, use of the term is a conscious reversal of common assumptions of anthropocentrism or human exceptionalism, and may be an example of an exonym.
