If you were on the side opposite Earth you would never see it, just as we never see the far side of the Moon from Earth. If you were at another point on the hemisphere of the Moon facing Earth, the Earth would be somewhere other than overhead but would still not move across the sky. There would be no Earth rise or Earth set. Since the same side of the Moon always faces us, you would see the Earth directly overhead at all times. Now imagine yourself on the Moon's surface exactly in the center of its disk as seen from Earth.

This, combined with the fact that it takes 29 1/2 days to complete one cycle of phases, means that anyone on the Moon's surface would see 29 1/2 days go by between consecutive sunrises or sunsets. As the Moon orbits Earth, it always keeps the same side facing us.

As phases continue past full, and you see the moon go from full to waning gibbous to third quarter and waning crescent, anyone on the Moon's surface at the terminator would see the sun setting. Anyone standing on the surface of the moon would see the sun gradually rise as the terminator passes them and the area goes from dark to light. Just watch the Moon each night from your backyard, noticing the movement of the terminator (the moving boundary between light and dark, not Arnold) as its phase changes from crescent to first quarter to gibbous to full. If you lived on the Moon, would you see the sun rise and set? how about the earth?
