* The Sun is a star: It generates its own light and heat through nuclear fusion.
* The Moon is a large, rocky body: It doesn't have its own light source.
* Reflection: When sunlight hits the Moon's surface, it bounces off in different directions. This reflected sunlight is what we see from Earth as moonlight.
Think of it like a mirror reflecting sunlight into your eyes. The mirror isn't producing the light, it's just redirecting it. The Moon does the same thing, but on a much larger scale!
