They have some information about the age and composition from the moon rocks they brought back. The number of craters and their shape also helps determine age and composition. They know the atmosphere, the total mass, the rotation speed and the distance from earth. All these things help in developing a theory on how the moon was formed. It is widely accepted that the Moon formed from an impact to the Earth, when it was still molten. Evidence of this is from extremely similar composition of the Earth and the Moon, and the fact that the Moon is slowly drifting away from us.
Scientists believe that the Moon formed about 4.5 billion years ago through a process known as the giant impact hypothesis. This theory suggests that a Mars-sized body, often referred to as Theia, collided with the early Earth, ejecting a significant amount of debris into orbit. This debris eventually coalesced to form the Moon. Evidence supporting this hypothesis includes the similarities in isotopic compositions between Earth and Moon rocks.
Scientist theorize that a planet-sized object collided with earth and the moon formed
We're not exactly sure, but it seems most likely that the moon was formed early in the Earth's history, when a large body collided with the Earth, shearing off molten debris. This molten debris formed the Moon. Most research and models show that the moon formed either at the same time or shortly after the Earth.
Scientists found evidence in Rodinia in Antartica.
One piece of evidence that suggests the moon was not formed from an accretionary disc is the similarity in isotopic composition between the Earth and the moon. If the moon had formed from an accretionary disc, it would likely have a different isotopic composition than the Earth.

Scientist theorize that a planet-sized object collided with earth and the moon formed
The moon was thought to have formed 4.527 billion years ago, when a large planetoid the size of mars collided with the earth, as the solar system was still in its infancy. The remains of this impact went into orbit around the Earth, forming into the moon we have today.
No one really knows how the Moon was formed. There are a few different hypothesis but not all scientists agree on one. Wikipedia has a short version of 4 of them.
Evidence for the fission theory of how the moon formed includes the similarities between the isotopic composition of the Earth and the Moon, the Moon's low iron content, and the Moon's synchronous rotation with Earth. Additionally, computer models of the early Solar System dynamics support the fission theory as a plausible explanation for the Moon's formation.
Scientist knowwhat the moon's crust is made of because the visited the moon's surface before.

There is no evidence that the moon has ever left its orbit since it formed, and there is no reason to expect that it will leave its orbit anytime in the forseeable future.
The maria's on the moon were formed by meteors slamming into it.
The scientist often attributed with forming the scientific method is Sir Francis Bacon, an English philosopher and statesman. He emphasized the importance of empirical evidence, experimentation, and inductive reasoning in the pursuit of scientific knowledge.
The evidence helps scientists come up with explanations about the natural world
I'd have to say the first scientist who saw the moon was the first one to look up in the sky...
