The following animation illustrates what most people probably understand about how the Sun, the Moon, and the Earth move. The Sun is at the center. The Earth orbits around the Sun, and the Moon orbits around the Earth. The Earth also rotates about an axis as it spins, which you can also see, because the green city appears to rotate.
So this is your first view of how the Sun, Earth, and Moon move. And, as you sit in your green city, you are spinning around and around.
