3. How does Earth’s rotation affect our view of stars
Elis [28]
Since we ride along with the Earth while it's doing whatever it does,
the Earth's rotation causes our eyes to constantly point in a different
direction.

direction of our eyes to keep looking at the same star. 

We can't feel the Earth rotating, so our brains say that the star  ... and
the sun and the moon too ... is actually moving across the sky.
