How and why does the moon move across the sky at night?

Question

I know I sound very dumb asking this but I am still confused at how the moon moves across the sky at night. I just don’t understand how it works, is it perception? The way the sun reflects light off the moon? I know the moon orbits around the earth every 28 days but it makes no sense to me. Many thanks.

The moon is indeed orbiting the Earth, but that’s not what explains that it moves across the sky. This is due to the rotation of Earth, just in the same way as the sun moving across the sky is the consequence of the rotation of Earth.
