Billions of year ago, when the Earth was still molten, a Mars-sized object collided with Earth ejecting material into orbit. This material coalesced to form the Moon. The Moon was once much closer to the Earth, but due to the tidal bulges of the Earth and Moon, the Moon moves farther away (about 1.5 inches) every year.
They do. Six of the eight planets in the solar system have moons and five of them have large moons. If you are asking why no planet has moons exactly like those of Jupiter, each moon has its own unique history, often interacting with its neighboring moons. So no two moons are alike.
The general tendency is for a more massive planet to have more moons. However, the number of moons will also depend on the planet's previous history, so the situation is not entirely straightforward.

High crater density is associated with older surfaces

By studying a planet's moons, you can learn about the planet's composition, mass, and possibly its history. The moons' orbits and sizes provide clues about the planet's gravitational pull and overall structure, while their surface features and composition can give insights into the planet's geology and environment.
The greater the crater density, the older the surface must be old.
