Here of late, it seems that every year or two, someone puts out a new theory of how our moon formed. Just a year ago, a group of researchers from the University of Bern proposed a theory that the earth once had two moons following an impact with the earth. Other theories of the past include other collision scenarios as well as the earth capturing a stray celestial body.
One of the most prevailing theories is that there was some type of collision with the earth that caused an ejection of material that coalesced into the moon. These theories involve a slow moving object about the size of Mars, which has been dubbed Theia, crashed into the earth when it was quite young.
These theories have their problems, some of which involve the differences in isotope compositions between the earth and the moon. Even though both the earth and the moon have iron cores, the iron isotopes in outer layers differ. Yet, when they look at oxygen isotopes are compared they are identical as are the titanium isotope ratios.
These similarities are the reason many evolutionists believe that the moon was formed in some way from earth material. However, there are differences in some isotopes between the two which is what creates part of the problem with the theory.
Now it’s time for another theory on how the moon came to be. This time, it comes from a group of researchers from Center for Space and Habitability in Bern, Switzerland. Andreas Reufer and his team have been running a series of computer simulations involving a collision with the earth and believe they have found new answers to explain the formation of the moon.
According to their simulations, they found that the moon may have been the result of a body larger and traveling faster than Theia impacting the earth. However, in their model, the impact was more of a glancing blow rather than a more direct hit. This larger body would have continued on its journey into space after losing only a small amount of material in the impact.
This glancing impact would have created a hotter disc of debris which then would have coalesced into the moon. However they still have an issue with the isotope ratios. This model also requires closer isotope ratios between the earth and the moon than what has been found by studying lunar samples that have been retrieved during earlier missions to the moon. They say that there needs to be more studies of lunar samples and more computer simulations to help fine tune the model.
In a time when the economies of many nations are in trouble, millions of dollars and thousands of man hours will be spent on trying to pursue this new theory of the Moon’s origin and structure. Yet, for less than $50 and no more than several minutes, they could find the answer to their burning questions. All they need to do is read the verses in Genesis 1 that tell us:
In the beginning, God created the heavens and the earth. Gen 1:1
And God said, “Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs and for seasons, and for days and years, and let them be lights in the expanse of the heavens to give light upon the earth.” And it was so. And God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars. And God set them in the expanse of the heavens to give light on the earth, to rule over the day and over the night, and to separate the light from the darkness. And God saw that it was good. And there was evening and there was morning, the fourth day. Gen. 1:14-19

Genesis teaches that God created the entire universe supernaturally, only thousands of years ago. Yet, most people are convinced that the universe started in a big bang billions of years in the past. In this illustrated lecture, astronomer Dr. Jason Lisle shows viewers that when the evidence of nature is understood properly, it lines up perfectly with the clear teachings of Scripture. The heavens declare the glory of God!
