Here's a breakdown:

* The Moon doesn't produce its own light: The Moon shines because its surface reflects sunlight.

* Sunlight reaches the Moon: Even when the Sun is shining brightly in the sky, its light still reaches the Moon.

* Reflected light is visible: The Moon's surface reflects some of that sunlight back towards Earth. If the angle is right, we can see this reflected light even during the day.

However, there are some factors that affect our ability to see the Moon during the day:

* Moon phase: We are more likely to see the Moon during the day when it's in its full or gibbous phases, as it's reflecting more sunlight.

* Position in the sky: The Moon's position in the sky relative to the Sun also matters. If it's close to the Sun, it's harder to see.

* Weather: Clouds can block our view of the Moon, making it harder to see during the day.

So, next time you see the Moon during the day, remember that it's still reflecting the same sunlight that's making the day bright!
