Someone asked, if life is abundant in the universe why we are not surrounded by other life forms? Considering that the habitat must allow for variety, IMO the earth is a perfect example of hosting an incredible variety of life forms. I believe a great case can be made that any planet with a life sustaining atmosphere will have some form of life. Of course the question is if Man is the supreme intelligence or if there are species elsewhere who would consider us bumbling fledglings. We speak of other life, but we don't even uderstand intelligence. Question: at what point does "ability to change information" (quantum) become intelligent, and at what point does it become self-aware (conscious thought)?
