I met some guy who said he lived in space but he was an Earthling before that, so it never hurts to double check! They could have been some earth colony in space or whatever. [Really the idea of humans being all over space is weird enough. Aliens are a take right out of science fiction.]

Besides who calls themselves "The Guardians"? Makes them sound like some fancy club of knights not a species of people in outer space. Do they have armor and ride around on space horses? [Does space have horses?]
