Parker has done an outstanding job of pulling together the current scientific understanding of life on Earth and the possibilities of life elsewhere.

I read the book with great pleasure... delightful to note how skillfully Parker analyzes and debunks many of the myths about the universe. Should be required reading for all who want to separate cosmic truth from fiction
