The first alliens are worms, ants, and spiders, they can live in outer space now. The human being is an allien brought down from space a long time ago.
We have not made contact with any aliens.
"Cowboys and Aliens" is about an invasion of Earth by extraterrestrials. What makes this a refreshing film is that the time is 1875 and the place is the New Mexico Territory. The movie stars Daniel Craig, Harrison Ford and Olivia Wilde.

The best, most scrupulously skeptical fact available, is that no one is known to have been abducted by aliens. Neither Venus or Pluto is likely to have any form of life, let alone life that could survive on Earth. In fact, there is, at this time, no reason to assume there are any aliens. Someone has to be the first form of intelligent life in the universe, and there is no reason to think we aren't it.
No, there is no subject. Who arrived?"Bob and Sara arrived exactly at their cut off time.""They arrived exactly at their cut off time."Arrived exactly at their cut off time is not a correct grammar.
