The same way we are able to see any celestial body... by meeting the conditions of luminosity and size. Sometimes we only see half a moon because the light from the Sun is only shining on one side. You seem to have a short memory because I've never denied that we need light to see anything in the external world.Hey, @peacegirl look up! There’s the moon! The moon is not a light source. But according to you, light does not bounce off objects.
How do we see the moon?
The Moon's phases are a result of the Moon's orbit around Earth and its illumination by the Sun. As the Moon orbits, different parts of it are illuminated by the Sun, creating the different phases we observe. The Moon does not produce its own light; it reflects sunlight. The illuminated portion of the Moon continuously changes its orientation relative to Earth as the Moon orbits, which dictates which parts of the Moon's illuminated half are visible from our vantage point. This changing geometry, combined with the Moon's position relative to the Sun and Earth, results in the eight main Moon phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent.
