It appears this accomplished scientist does not agree with you either... Nor does he entirely agree with my position, but at least this man does not dismiss the obvious.
"Nobel Laureate: No Inherent Conflict between Science and Religion"
On June 13, 2005, Nobel laureate Charles H. Townes, inventor of the laser, spoke before a full house at Harvard University's Science Center on the topic "Logic and Mystery in Science and Religion." The main thrust of his speech was that science and religion are not mutually antagonistic disciplines. During his 40-minute address he stated: "I look at science and religion as quite parallel, much more similar than most people think and that in the long run, they must converge" (Powell 2005: 5).
In his speech, Townes stated (as paraphrased by the Harvard Gazette) that both religion and science "deal with large, unproved mysteries, and operate on the best knowledge available today. Faith is a central tenet of religion, but Townes said a certain amount of faith is also shown by scientists, applying theories that they know have shortcomings in an effort to understand the vast amount of the universe that remains unknown" (ibid.).
The Gazette further reported: "Among the parallels cited in his talk, Townes said that science has proven that in the big bang, there was a 'creation,' though not one described in creation stories such as the Bible. He also said that there's very little wiggle room in the laws of nature in order to allow life to arise, which prompts questions of why they are the way they are. Questions about free will, the nature of consciousness, the forces that caused the big bang – or even what came before the big bang, highlight the vastness of what humans don't know about the universe – whether from a religious or scientific standpoint, Townes said" (ibid. 6).
"Scientists, especially physicists," Townes stated in his speech, "recognize that this is a very special world. Things have to be almost exactly as they are in order for us to exist. It's a fantastically specialized universe, but how in the world did it happen?" (ibid. 6).
Townes is no slouch when it comes to scientific achievement. He won the 1964 Nobel Prize in Physics while at the Massachusetts Institute of Technology "for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle" (ibid. 5). Donald H. Menzel Professor of Astrophysics James Moran of Harvard, who introduced Townes' speech, described him as "one of the founding fathers of radio-astronomy" (ibid. 5).
Townes is one of a growing number of top-ranking scientists who have publicly dismissed the common claim that science and religion are necessarily and perpetually antagonistic. True, Townes has not embraced the Biblical version of the origin of the universe, but he has nonetheless demonstrated that an accomplished scientist need not reject religion out of hand.

They make the mare side of the Moon the heavier side.

OK Tom,
No more God talk from here on out. I see that this site is not open to certain differing views. I suspect it can only be because certain views are a threat to the status quo. For those of you reading this who are actually open to the possibility that the evolutionary, exploded planet, Oort cloud theories could just possibly be incorrect, you can find an alternative and competing theory well backed with documented scientific data elsewhere. Go back and read my previous posts to find out where to find it.
Tom,
The moon explanation is impressive. I can actually picture that. However, that is what one must do, because we can not say for certain that the moon ever rotated as you say, because it has never actually been observed. We can imagine it. We can theorize it. We can infer it, but that is it. It is not fact. I say the moon has never been a rotational body, and since it does not rotate today, I'd say my view has equal weight. Funny how evolutionary science is very uniformitarian, except when it does not fit the model.
What caused this planet to explode anyway? Do you have any pictures of other exploding planets out there? Why the "fourth" planet fromt the sun? What could possibly generate such a force that would not only explode the planet, but scatter it also. Why didn't it gravitationally collapse back onto itself? How does ice still remain on the moon and Mercury from a planet that exploded 3.2 million years ago? How did life on earth survive this event? Is there evidence of a mass extinction 3.2 million years ago? Why don't we see evidence of mass cratering/meteors in the geological record at 3.2 million years? How did comets form from this explosion? And you have not addressed a key question - If the many comets in Jupiters family are only expected to survive for about 12,000 years on the average, how could they have been around for 3.2 million years? They are short period comets, and it is nearly impossible for a long period comet to become a short period comet, so most started out as short period comets. They should have all been destroyed if they have been around for as long as your theory claims.

Tom,
Just for the heck of it, can you imagine any possible mechanism (within the laws of physics) that would cause a comet to traverse a 3.2-million-year orbital path in less than 3.2 million years?
