The Fission Theory: This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came. This theory was thought possible since the Moon's composition resembles that of the Earth's mantle and a rapidly spinning Earth could have cast off the Moon from its outer layers. However, the present-day Earth-Moon system should contain "fossil evidence" of this rapid spin and it does not. Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received.
The Capture Theory: This theory proposes that the Moon was formed somewhere else in the solar system, and was later captured by the gravitational field of the Earth. The Moon's different chemical composition could be explained if it formed elsewhere in the solar system, however, capture into the Moon's present orbit is very improbable. Something would have to slow it down by just the right amount at just the right time, and scientists are reluctant to believe in such "fine tuning". Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received.
The Condensation Theory: This theory proposes that the Moon and the Earth condensed individually from the nebula that formed the solar system, with the Moon formed in orbit around the Earth. However, if the Moon formed in the vicinity of the Earth it should have nearly the same composition. Specifically, it should possess a significant iron core, and it does not. Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received.
The Bible theory: God created it in the 4th day.

What was the great disappointment?
A certain William Miller - and his followers - believed that Jesus Christ would return in 1844. The Great Disappointment means that the foretold time passed, and William Miller and his followers believed that Jesus Christ had NOT returned.
What event led to the formation of our solar system, including the keyword "formation"?
The formation of our solar system was triggered by the collapse of a giant molecular cloud, leading to the creation of the Sun and its surrounding planets.
Where did the singularity come from and how did it impact the universe?
The singularity, a point of infinite density and temperature, is believed to have originated from the Big Bang, the event that created the universe. The singularity's rapid expansion led to the formation of galaxies, stars, and planets, shaping the universe as we know it today.
