The word 'extraterrestrial' means anything from beyond planet Earth. It is often used to describe things related to life or objects that may exist on other planets or in space. For example, if someone believes in the existence of aliens, they might say, "I think there could be extraterrestrial life out there." The word can also be used to describe UFOs (Unidentified Flying Objects) or sightings of strange objects in the sky that people believe could be from outer space.
