You're wrong.
You worried that you might come into contact with people from another planet, but instead of a spacecraft you are met with an ever-growing blackness. The dark square expands quickly, covering the sky. The clouds are blocked out, as is the sun, and the field slowly darkens. Part of you wants to run, but you know that you can't escape, and even if there was a possibility of survival your legs aren't paying attention to your mind. So you stand there like a deer in headlights, aware of your fate yet still befuddled, as you watch the apocalypse roll in.
Soon all life will be over.
Sorry about that.
GAME OVER.
