Giant Impact, Big Splash, or Theia Impact.
The giant impact hypothesis states that the moon was formed after a planet called Thei slammed into the Earth right after the Earth came into existence.
The Giant Impact Hypothesis
They generally don't. The Giant Impact Hypothesis is generally accepted amongst scientists.
The most common term is probably "Giant Impact Hypothesis"; another term sometimes used is "Theia Impact (Hypothesis)", with "Theia" being the name of the proposed body that impacted the proto-Earth to "splash" out the Moon.
There are four main hypothesis for the formation of the moon. ; Fission hypothesis - The Moon broke off from the Earth ; Capture hypothesis - The Moon was captured ; Co-formation hypothesis - The Moon and Earth were created at the same time ; Giant Impact hypothesis - The Moon was created when a Mars sized object (Theia) crashed into the Earth.

Robert Wadlow's nickname was the "Alton Giant" or the "Giant of Illinois."
The giant impact hypothesis proposes that the Moon was created out of the debris left over from a collision between the young Earth and a Mars-sized body. The colliding body is sometimes called Theia (or Euryphaessa) for the mythical Greek Titan who was the mother of Selene, the goddess of the moon.[1][2]
