※ Cradian (Cradlian) A common term used by space travelers to refer to Earthlings, regardless of whether they come from the Moon or Mars. Literally, it means "people of the cradle." "The Earth is humanity’s cradle. However, humanity will not remain in the cradle forever." This originates from a famous quote by Tsiolkovsky. It carries the nuance of referring to Earthlings as those still in the "cradle" (Cradle), implying that they are immature beings who have yet to leave. Initially, it was simply used to mean "baby," but due to the mixed connotations, it eventually fell out of use.
