Why am I classed a SciFi Movie Extra & Terrestrial Classes of 3!

Believe it or not an extraterrestrial is a special class of entity for scifi movie extra normally that have a habit in movie distribution and transposition of ending up in the most awkward position and places where they look out of appearance and often have little or no refuge, normally you would have an outerterrestrial which is for an entity from your galaxy but not your native solar system or star base, or you have an ultraterrestrial which is from outside your own galaxy that is native!
