Looking up to the moon, I always wonder what lies in the heavens behind; other planets with moons like ours? people like us? We will probably never know, not of because of the distance in light years, but because other civilisations will have to make it through the stage that we are facing: Trying to make a sustainable world for the inhabitants on the long run. And in my opinion it is not sure that we are going to make it ourselves. A saddening thought, soothed by the moonlight that will longer be here than us.
