The Moon is the natural satellite of the Earth. The moon is the only place other than Earth where humans have landed. The surface of the moon has large relatively dark “Maria” which are lava fields and numerous impact craters caused by meteor bombardment.
What we see
What we see is the near side of the moon, or the side that is always faced towards Earth due to the Moon's synchronous rotation.
Westerners sometimes think they can see a man in the moon. Asian folklore (probably Japanese) tells the story of an apparently gigantic rabbit that somehow got stuck on the moon, and as a result, we now can see it chilling up there. If there really is anything in the Moon, it's obviously just a bunch of craters shaped like whatever.
Also, various accounts of cheese falling from the sky indicate that the moon may be constructed out of the dairy product.
