Answer 1

The best explanation for why we see the Moon at different phases is: we only see proportions of the Moon that are reflecting sunlight.

The phases of the Moon are caused by the relative positions of the Earth, Moon, and Sun. As the Moon orbits the Earth, different portions of its surface are illuminated by the Sun, leading to the various phases we observe (such as new moon, crescent, first quarter, gibbous, and full moon).
