The evidence in Gonzales’ book is far from “overwhelming”. If you don’t understand the meaning of “exoplanet”, then you are probably underqualified to pass judgement on the book. It is a book about science, and if you do not understand enough science it will be difficult for you to see the flaws in Gonzales’ arguments. For a sceptical review of the book see Review - The Privileged Planet.First of all, to make the discussion more accessible to amateurs like myself who don’t understand at a glance words like “exoplanet,” the word simply means planets outside the Solar System. rossum, it seems incredible to me that after reading Privileged Planet you think the overwhelming body of evidence contained therein can be rendered obsolete by a mere increase in the number of discovered planets.
There is a story of a Medieval monk who argues for the existence of God from the fact that He had placed a river through every large city for the convenience of its inhabitants. That argument fails, as does yours here. Earth is suitable for life because life on Earth has evolved here. Life has adapted to Earth, so Earth is indeed very suitable for life on Earth, just as cities were built on pre-existing rivers. There were times when Earth was very unsuitable for human life; study the Oxygen Catastrophe which wiped out a large proportion of the life then on Earth and greatly changed the composition of Earth’s atmosphere.As I summarized in the OP, it inferred design from the unnecessary pattern of correlation between Earth’s unique suitability for life and scientific learning.
Gonzales’ argument relies on a knowledge not just of life on Earth, but of all possible forms of life. What conditions are suitable for some alien form of life? Since we cannot know how many possible forms of alien life there are we cannot tell how many planets may be suitable for one or other of those forms of life. Perhaps a silicon based life form might find Mercury a little on the chilly side. Something like Hoyle’s Black Cloud could live in interstellar space.
You speak of “life-essential qualities”. Tell me, what are the “life-essential qualities” for the alien Pazaxi who live on a planet in the Andromeda galaxy? Unless you can tell me the answer to that question, then any probability calculations made on the basis of “life-essential qualities” must be faulty because one of the terms is unknown.You tell the forum there is a growing list of planet candidates, and concerning some of those planets the scientists are still debating whether or not it is a gas giant. These planets are so far away, it’s hard to even clearly see their existence, let alone get near determining whether they have a fraction of these life-essential qualities. It is incredible to me that you disregard the book’s argument out of hand with such weak evidence.
