They don't live here. Every one of them wants to escape, duty-free, from this lump of rock on the very next comet that comes by. Or on the New Age Cruiser that's actually hiding behind the comet. Or maybe it's a Ramadan Rocket. Not a one of them expects to be forced to actually live in this world, at least not for very long.
Angels is the alien term.
Talk to them. The best you can get are a couple of interpreters who try to translate the native language to the few aliens who are interested. The rest of these aliens speak the native tongue in, at best, a sort of pidgin, and are quite proud of themselves for not understanding it. They're just visiting, after all. Besides, the native language doesn't have words for all the things the aliens hold dear, like absolute truth, omnipotence, revelation, family values, sin, resurrection, nirvana, samsara, avatar, certainty, gods, devils, angels, papal infallibility, missionaries, good, evil, heaven, hell, judgment, holy, sacred, jihad, rosary, prayer, worship, submission, reverence, devotion, invocation, absolution.
