quote: The Earth's solar system is far from unique, and it is possible there could be billions of habitable planets -- many of which have obviously not been identified.
quote: It is unlikely that there are many that we could live on, because of our delicate pH balance and Atmosphere needs, as well as the small temperature range in which we can survive, along so many other reasons, but there is no reason that some sort of life cannot live on another planet. Life itself is only something that practices self preservation and reproduces. If any planet has anything that can do those two things, then it is habitable for that lifeform at least.
