People from outerspace. Generally peace loving and wise, they've come to Earth because we've got velcro and they love that shit

1. In terrestrial terms, those who come from another country, a.k.a. immigrant.

2. Usually refers to any being that isn't from the planet earth, a.k.a. extraterrestrials (E.T.)

An excellent science fiction movie series. Features a race of insect-like aliens called Xenomorphs, which have acidic blood and a collective mentality. They lay eggs like normal insects, but the larvae can only mature into adults by leaping onto a host organism's face and injecting themselves dow into the digestive tract. The adults burrow themselves out of the host, killing it in the process.
Basically, if you have an alien Xenomorph on your planet, your species is doomed.

A creature from another planet. It doesn't have to be a smart one. Unlike the lies that media bullshit tells you, aliens would NOT look like us, they would look completely different, so that they could adapt with the conditions on their planet. Also, just because we are carbon-based doesn't mean that they are.

something that exists on europa and at area 51. Living things from another planet. Also people from a different country.Yea. but in 1960 there was a ufo crash (yes a lot of those videos are fake but some have yet to be proven wrong) in new mexico and a guy got some crazy footage, but the government took it all away and the guy mysteriously died (government killed him). Also an f16 in isreal chased one but the f16 vanished... also another case in which a pregnant lady claimed to have been abducted, and lost the baby and became not pregnant... then 8 years later she saw the daughter in a ufo. You cant make up losing your pregnancy. yea well anyway there are too many planets to not have there be life anywhere else. why do you think area 51 has a zone where if you pass it you get shot? and they have soldiers that blend in with the ground and mountains
