As he looked out the airplane porthole onto landscape divided, subdivided, and settled on in various ways, he felt a sudden tug to see humans as aliens who had indeed landed millennia before and turned Earth into a parking lot.  As the plane kept ascending, he felt a sudden fear that it wouldn't level off, or ever land, that everyone on it was cargo aliens commonly abduct to have reprogrammed.  He looked back into the cabin to get a close look at the steward and stewardess.  She was leaning down to hand a girl much littler than he a surprise treat.  The girl grasped at it with both hands and delightedly slammed it to her face.  He thought her cute when she cried, and then he turned and looked back out the window as the plane leveled off upon a pristine mountain range just coming into view.
