"Planetary scientists invented the idea that the moon formed after a collision between the earth and a Mars-sized object. It is called the ‘giant impact hypothesis’ and has been the reigning model for the past 30 years. Some have come to believe this hypothesis as a fact.However, the identical isotopes of various elements between the earth and the moon indicate that the giant impact hypothesis has serious problems.
Astronomers are discovering more and more that the geochemistry of the moon is almost exactly that of the earth:
“A crisis in the field has been created by the growing realization that the Moon and Earth are exceptionally similar in composition—so similar, in fact, that the emerging constraints are difficult for the giant impact hypothesis to meet. … The Earth and Moon seem to share identical isotopic signatures in oxygen, iron, hydrogen, silica, magnesium, titanium, potassium, tungsten and chromium. … That all these isotopic compositions are the same on the Earth and Moon, to high precision, places stringent constraints on physical scenarios for making the satellite.”Such exactness defies the giant impact hypothesis because models have concluded that most of the moon should have been created from the debris of the impactor, and therefore the geochemistry would be significantly different.
Older theories are still seen as implausible:
“Competing hypotheses, such as fission of the moon from a de-spinning earth or capture of an unrelated Moon into orbit around earth, do not fit as many of the required constraints, and require special pleading on several fronts.”It seems that the main reason scientists have been unable to explain even the closest body to the earth, the moon, is their naturalistic worldview: “we want to explain our Moon and earth as the outcome of a common and reasonable process”. The failure of naturalistic models is implicit support for the Genesis record of creation of the moon by God on the 4th day of creation, an idea unfortunately unthinkable to naturalists." CMI
