Gaea, the earth, came out of darkness so long ago that nobody knows when or how.  Earth was young and lonesome, for nothing lived on her yet.  Above her rose Uranus, the sky, dark and blue, set all over with sparkling stars.  He was magnificent to behold, and young Earth looked up at him and fell in love with him.  Sky smiled down at Earth, twinkling with his countless stars, and they were joined in love.  Soon young Earth became Mother Earth, the mother of all things living.  All her children loved their warm and bountiful mother and feared their mighty father, Uranus, lord of the universe.
