1. Sunlight: The Sun emits a vast amount of light energy.
2. Reflection: This sunlight travels through space and reaches the Moon. The Moon's surface is dusty and rocky, and it reflects some of this sunlight back towards Earth.
3. Journey to Earth: The reflected sunlight travels from the Moon to Earth, taking about 1.3 seconds to complete the journey.
4. Reaching our Eyes: When this reflected light reaches our eyes, we perceive it as the Moon's glow.
So, in short, the light we see from the Moon is simply sunlight that has been reflected off its surface. This is why we only see the Moon during the day or night when the Sun is shining on it.
