Here's why you might see stars when looking at the moon:

* Stars are always there: Stars are constantly shining, day and night. Even during the day, the sun's light overwhelms the faint light from the stars, making them invisible.

* The Moon Doesn't Block Stars: The moon itself doesn't block out starlight. It's a relatively small object in the sky, and the stars are so far away that their light can easily pass around the moon.

* Atmospheric Scattering: The Earth's atmosphere scatters light, especially blue light, which is why the sky appears blue. When you look at the moon, you're also looking through the atmosphere, and some of the light from distant stars is scattered towards your eyes. This makes the stars appear fainter and "twinkle".

In short, you don't see stars "between" the Earth and the moon; you see them through the atmosphere, even when the moon is in the sky.
