Only about one in every 10 to 20 solar systems may harbor a similar moon.

The Moon is truly unique. It's close enough to Earth to cover the Sun's disk so that during total eclipses we can measure the Suns's gravitational bending of distant starlight consistent and confirming of General Relativity.

The Moon stabilizes the Earth's tilt which give us the seasons, and it may act too, gravitationally, to modify plate tectonics within the earth, without which, human life could not have been possible.

Combined with all the other "coincidences" which give us the life we know, is more evidence than not, for the existence of God.

Extrasolar Planets: Testing Models of Planet Formation -- "Roche Limit & Migration... Circularization of highly eccentric orbits with small pericenter distances: Predicts edge at twice the Roche limit, Planet-planet scattering, tidal-capture of free-floating planets... Formation of Uranus & Neptune, Problem: Standard timescale to accrete Neptune in situ at ~30 AU exceeds 4 Gyr... Our own solar system may have once contained giant planets on eccentric orbits."

Chinese Scientist Gives New Hypothesis on Origin of the Moon
People's Daily
Thursday, November 29, 2001
A planet collision may have helped form the Moon. This is the new hypothesis on the origin of the Moon by Huang Jinzhong, a geographer from the Seismology Bureau of Quanzhou City. Huang said two planets, between the orbits of Mars and Jupiter, collided and split some 4.6 billion years ago, and one of the fragments formed rudiments of the Moon. Huang supported his hypothesis with evidence of the Moon's internal structure and chemical components, the age of rocks on the Moon, and other geological data. A planet collision may have helped form the Moon. This is the new hypothesis on the origin of the Moon by Huang Jinzhong, a geographer from the Seismology Bureau of Quanzhou City, Fujian Province, according to latest issue of Beijing Review.
Rudiments of the Moon Comes From Fragments
In a paper submitted to the annual meeting of the China Association for Science and Technology (CAST), Huang said two planets, between the orbits of Mars and Jupiter, collided and split some 4.6 billion years ago, and one of the fragments formed rudiments of the Moon.

This rudiment Moon was a melting celestial body, circling the Sun, according to Huang. Influenced by Jupiter's gravitation, its orbit began to change. The rudiment Moon collided with the South Pole region of the Earth some 4.46 billion years ago, and rebounded from it. The rebound force and Earth's centrifugal force then caused the Moon to circle around the Earth, he said.
Evidence from Structure & Chemical Components
Huang supported his hypothesis with evidence of the Moon's internal structure and chemical components, the age of rocks on the Moon, and other geological data. Huang's hypothesis on the origin of the Moon comes from his theory of the genesis of the Solar System. Japanese geologist C. Hayaci said Huang's theory is an innovative school of thought in the field.

There have been four hypotheses on the origin of the Moon so far: First, the Moon was a fragment separated from the Earth; second, the Moon was an independent planet captured by the Earth's gravitational pull; third, both the Moon and the Earth were formed by the same cluster of celestial material; and fourth, the Moon was formed by substances sent out after a huge planetestimal collision with the Earth. Yet all of these theories are considered flawed in certain aspects.

Your pix reminds me of Sitchin's mythtalk and is similar to Tiamat getting side-swiped by Marduk (Nibiru). The collision takes place in the asteroid belt during one of Marduk's 3,600-year orbits, shattering half of the planet which caused the asteroid belt, and pushing the other half into an orbit between Mars and Venus, later becoming Earth.

The moon was one of the larger bodies orbiting Tiamat and was captured by Marduk after the collision, but only briefly, as it joined with Earth to share the new orbit of the remains of Tiamat. The center of balance (I forget what it's called) is a mile or two beneath the Earth's surface.

There is, alas, no Marduk and there was no Tiamat. :’)

The man wrote 9 books or so. I don't think anyone can research as much as he did and write nine books that contained not one iota of truth. Pretty hard to do. The thing is, what is that one iota of truth that is contained in myth. Even a clock is right once a day.

Sitchin bases all his books on his entirely made-up line of bull about a fictional planet with impossible orbital characteristics. :') And then there's this, which I reprise here and there:
Zecharia Sitchin's Errors: An Overview
by Michael S. Heiser
The study shows - from the texts themselves, not my opinion - that "Nibiru" is not a planet beyond Pluto and that the Anunnaki gods are never associated with it. These ideas are fabrications... This study details the impossibility of Sitchin's translations of "nephilim" as "those who came down" or "people of the fiery rockets" in light of Hebrew vocabulary and grammar. I know it sounds mind- numbing, but again I have tried to illustrate the concepts and problems. It also contains a scan of a page from one of Sitchin's books where he could not tell the difference between Aramaic and Hebrew - an amazing mistake if he's an expert... Mr. Sitchin contends that the word "Nephilim" means "those who came down from above" or "those who descended to earth" or "people of the fiery rockets" (see The Twelfth Planet, pp. vii, 128ff.). These translations, of course, serve his purpose - to see the Nephilim as ancient astronauts. As such it is hard to over-estimate the importance of Sitchin's work here - if he's wrong about the meaning of "nephilim," much of his overall thesis falls... Sitchin assumes "Nephilim" comes from the Hebrew word "naphal" (as opposed to ARAMAIC - see below) which usually means "to fall." He then forces the meaning "to come down" onto the word, creating his "to come down from above" translation. "Nephilim" - in the form we find it in the Hebrew Bible - COULD come from Hebrew "naphal," but it could ONLY mean be translated one way in light of the spelling - "those who are fallen" (i.e., either "fallen in battle" - which is out of the question given the context of Genesis 6 - or "spiritually fallen" / evil - which fits the context IF the sons of God are evil)... In short, if you care about the grammar of Hebrew, Sitchin's word meanings CAN'T be correct. The above file also discusses Sitchin's confusion of the sons of God and the nephilim - and evidence from his own book, Stairway to Heaven, that he cannot distinguish between Hebrew and Aramaic! My suspicion behind this apparent blunder is that Sitchin wants to distance the Annunaki from the evil Watchers of ancient Jewish literature (Hebrew Bible, Enoch, and some Dead Sea Scrolls).

Thanks for the link. Going to read Chapter 1. May as well. I'm tired of re-reading Sitchin and didn't know there were any alternates out there, other than all of the lesser authors and novelists who attempt to put clothes on the ancient personalities, both real and mythological -- revealing their ongoing role in human affairs and current events.

I would offer a link in return, but the book I would recommend, "Godstone" by Tim Rivers and Joe Schultz isn't online nor has it been published. I have one of the manuscripts which has been passed around privately.

I believe it was Asimov who first brought to me the statement that our large Moon is very unusual, and possibly life-giving to Earth. If this turns out to be true, I’ll gain even more respect for him, even if it wasn’t an original thought of his.

A hypothetical body wandering in from interstellar space would most likely be moving far slower especially to be slow enough to either be captured in solar orbit or to not impart a solar escape velocity to an impacted early Earth.

Could it have been another planet still forming between Mars and Jupiter (in the asteroid belt), that perhaps got knocked out of orbit by other chunks still there before it was completed, or flung out by the push/pull of Jupiter's gravity on the one side, and the sun and inner planets on the other?
