'''Extraterrestrial life''' is [[life]], whether demonstrated, hypothesized, or merely imagined, that did not obviously originate on the [[earth]]. It has been a staple of [[science fiction]] since the [[Edward VII|Edwardian]] era, but has also lately become the subject of intense speculation, scientific debate, and even theological debate.

The term ''life'' is here used in its usual manner to connote living things, regardless of complexity or condition of sentience.  However, in [[science fiction]] especially, extraterrestrial life may take unconventional form, such as non-carbon-based life forms or even disembodied intelligence. The term ''race'' here means a species of sentient individuals (not an ethnographic subdivision of a single species); for example, humans all belong to only one race, the human race.
