Take a walk...
You walk all over the moon. The Earth looks beautiful. You see many
big caters and think of jumping into then, but you are afraid you
won't get back up. Then you notice a silver-blue circular thing in the
horizon. What can it be? You walk nearer. You smell something
peculiar. You hear some buzzing noises. You walk closer and see that
there is another circular thing, but it is glowing red. They are about
20 meters in width. Suddenly you hear someone shouting in a weird
language. You have never heard this language, but you can still
understand it. Someone asks "Who are you". You can't see
anyone...
