>As far as Carl Sagan being wrong, he was big on the idea that our subjective minds are just a thing that hydrogen atoms do, if you give them billions of years to do it. That is a beautiful thought. But it is not clear life is inevitable at all. We only have one example of a planet containing life. The normal flow of the universe is toward increasing levels of entropy. I suppose gravity wells containing stars reverse this on some scales. The early post big bang universe was in an extremely low entropy state. Personally I am not a materialist. I also do not believe that we know what we are talking about when we attempt to talk about consciousness. I think the noun is imprecisely defined.
