Dear Earthling, I've heard stories about your planet, Earth. Is it true that you can see greenery for miles on end? Do creatures called birds really gather together and sing to you in the morning like a choir? I've been told that if you look upwards, you can see a beaming blue ocean made out of nothing but fresh air that stretches out as far as your eyes can see. It sounds like heaven from over here.
