The moon has been our shadow for billions of years. But no scientists are completely sure how the moon was formed or it's origin. The four main theories focused on today are the Fission theory, the Capture Theory, the Co-accreation, and the Giant Impact Theory. However, the theory that is most accepted and most logical is the Giant Impact Theory.
The Fission Theory says George Darwin, son of Charles Darwin, made a theory that the moon may have looked similar to Earth because at one point, Earth may have been spinning so fast that part of Earth spun off into space but was kept there by the gravitational pull. Meaning, that the moon was once part of the Earth. Scientists began to to look into the theory because he

This lead the moon to make its way to the position in space it is now.
The scientists studied this theory because of the similarities in the chemical components of the
Earth and the Moon which suggested that they were made around the same time. However, they have all this evidence on some things,this theory is still not accepted due to the lack of evidence on how the Moon got separated from the Earth.
The Co-accreation Theory, which is also commonly known as the sister theory, believes that the Moon and the Earth were both formed together while orbiting a black hole, also known as the nebula. There is studies showing that these assign space objects were created together in the nebula, however it isn't enough evidence to fully accept this theory.
The Giant Impact Theory states that Earth and a Mars sized object collided together 4.5 billion years ago. When the collision happened, the debris from the impaction and the debris from the Mars sized object spun around in circles until it eventually formed the object we know as the moon. Scientists accepted this theory because there were astounding amounts of useful evidence coming from the studies done, and all the people who proposed this
