Earth gave violent birth to the moon

Researchers at Harvard have developed a theory to help explain the moon being born of the Earth.

When the planetary aggressor Theia struck the Earth, according to their model, it sends a disk of material spinning out around Earth’s orbit. But then, over hundreds of years, the disk cooled to form the Moon. At this point, the Moon’s own orbit began to expand outward, away from the Earth. Over the course of another ten thousand years, the Earth transfered angular momentum to the moon, slowing down Earth’s spin. During this phase, the Moon would have appeared about 20 times larger in the night sky, according to the scientists.

Then Carl found video. Not saying this is what happened exactly, but it probably went something like this.
