Here's how it works:
* Sunlight: The sun is a giant ball of fire that emits light and heat.
* Reflection: When sunlight hits the moon's surface, it bounces off, reflecting the light back towards us.
* Nighttime: We see the moon at night because the Earth is facing away from the sun, but the moon is still illuminated by sunlight.
Think of it like a mirror: a mirror doesn't produce light, it just reflects the light that hits it. The moon works in a similar way.
