Q: "What about Lunar Eclipses and Moon Phases?"
A1: The moon isn't a spotlight; it glows with light from the sun, reflected off the Earth. Different parts of the Earth are more reflective than others (the seas, the polar cap, the ice wall, for example). Sometimes, the position of the sun (which is a spotlight) means that only very low-reflective or non-reflective parts of the Earth's surface are illuminated, so the moon is abnormally dark. This could potentially explain lunar phases as well.
A2: An invisible celestial body, known as the Shadow Object, gets in front of the moon.
