Stonehenge is, apparently, trying to terraform the planet. Let me be clear - that planet is Earth.
Years ago, Jim and I saw a movie called Black Hole. We saw it in the theater (proving what happens when your friends get to pick the movie. I have many examples).
Early on, they stated that their mission was "to find habitable life in the galaxy." We made the same strangled not-laugh we just made. (everyone else thought there was something wrong with us.)
