You're right to think about this! It seems like we should be able to see the moon rotate, but there's a cool reason why we don't.

Here's the thing:

* Tidal Locking: The Moon is tidally locked to Earth. This means the same side of the Moon always faces us.

* Rotation Speed: The Moon rotates on its axis at the same rate it takes to orbit Earth. It takes about 27.3 days for both the rotation and the orbit.

Think of it like this: Imagine you're holding a spinning basketball. As you walk around the basketball, you only see one side, even though it's rotating. The Moon does the same thing with Earth.

So, while the Moon is definitely rotating, we only see one side because its rotation period matches its orbital period around Earth.
