Why are you here? Where did you come from? C: We have been observing you for the last three thousand years. We have seen the amazing capacity that humans have to create such won- ders as the Taj Mahal or masterpieces such as the Haffner symphony. Unfortunately, your intelli- gence and creativity does not come without con- sequence. Your ambition and desire for more will be your downfall, and we are here to save your planet from you.
