During the early stages of Earth's formation, a large body of mass struck the Earth and caused a large portion of it to seperate into a new orbit.
The moon most consists of the same material... all of which can be found here on our planet aswell.

In brief, a body the size of Mars hit the Earth, threw debris into orbit which later stuck together to form the Moon.
By suggesting one large impact this theory explains well why the Earth's rotation is as fast as observed today and also why the Moon has such a tiny metallic core given that the impact shaved off only the Earth's iron-depleted rocky mantles.
The bottom line is that the Earth and the Moon did not form together. In other words, they are not sister worlds as previously thought.

As any other celestal bodies in the Universe there is no ultimate theory. We can only speculate about Creation because we werenot there to withness. And what ever theory speculates about the moon can be also doubly wrong.
all we know about it is what it was designed for.

When the Earth was just being made, and it was still molten lava, another smaller planet crashed into it sending lots of lava in orbit around the Earth in a ring. Over time, the ring collected itself up with the force of gravity and turned into the moon when it cooled.

I can't tell you it is a secret.
