They call the Moon a moon because that was the only satellite ancient people knew about. The real answer is the word "moon" is derived from the Germanic word "me-" as in measurement. In its Latin form the word is "lunar". Some people say "lunar" is from lunatic, as a myth that some people go crazy on a night of the full moon.
