It is hard to know the exact situation before the big impact. However, most objects start with some rotation when they form from coalescing materials, and it seems unlikely that the Earth would have had enough time to slow down enough to have a synchronous rotation.

The Big Bang is the theory that was developed to describe the origins of the universe.

because the moons core is small, that means it didn't have any
The fission theory is a scientific explanation for the formation of the Moon. It suggests that the Moon was once part of the Earth and broke off due to a massive impact with another celestial body, leading to its formation. This theory is supported by evidence such as the similarities in composition between the Earth and Moon.
A theory of the origin and formation of the universe (the cosmos).

The Big Bang is the theory that was developed to describe the origins of the universe.
An asteroid/meteor impact is one theory. The truth is that nobody knows for sure, just like the exact origin of the moon is not known for certain.

There are six different stages in the condensation theory. These include the formation of a nebula cloud, the formation of a sun, the formation of planetesimals, the expulsion of gases from the forming sun, the growth of the planetesimals, and the formation of larger planets from planetesimals.
