What does rotation of the Earth mean?
The Earth spins at 1000 mph from West to East and it takes 24 hours to complete one full rotation.
If the Sun does not move, then why does your shadow move as the day goes on?
The sun did not move. It's the earth spinning that causes the sun to be shining on a different spot on the earth, which is why your shadow keeps moving directions. Since the earth spins in the same direction all the time, the shadow always moves in the same direction as well.
