I see what you’re saying but the Moon does present all sides to the Earth doesn’t it?
It is the Sun that one side of the Moon is always facing. No?
No, the same side of the moon always faces Earth. The phase of the moon is caused by the shadow cast by Earth as the moon orbits.
That’s where people get confused. I know someone already explained it to you, but I’ll just add that the ‘dark’ side of the Moon, while never facing the Earth, does face the Sun so it’s not always dark. I think many people believe it’s pitch black all the time on one side.
