I guess in the sense of this acrosstic, we are all aliens here... And I am not just talking humans. I've seen ants mount a rescue mission for their unborn young when I uncovered their nursery purely by accident. The entire colony immediately sprang into action and started picking up the eggs to carry them off into the dark safety of the lower regions of the nest.
And then there was the behavior of our poodle someday, who was playing with a ball. It rolled under the TV cabinet, which was too low for him to get under. He looked at it, decided it was too far under there to reach from the front. So he ran around it, pushed the ball from behind, and then ran back to the front to catch it again.
Likewise, crows are smart enough to combine tricks they learned separately, in order to solve a puzzle to get to food they want to have.
