The Earth itself is rotating @ 1 revolution per day -hence the 'Sun moving in the Sky': meanwhile the Earth is following an elliptical track around the Sun whilst itself spinning.
Because the earth is rotating thus creating the illusion that the stars are moving across the sky.
Its actually because the Earth is rotating.
Everything in the sky appears to be moving because Earth is rotating. BUT - also, Earth is orbiting the Sun, and the Sun and all the planets are rotating in an arm of the Milky Way Galaxy, which is also moving through the Universe....

Stars seem to move in the sky due to the Earth's rotation. It creates the illusion that the stars are moving across the sky when, in reality, it's the Earth that is rotating on its axis. This phenomenon is known as diurnal motion.
It is because the earth is rotating on its axis
Because the earth is constantly rotating so the sky itself moves
Because the earth is rotating.
the constellations aren't moving, we are. the earth is constantly rotating giving us day and night
The stars appear to shift in the sky due to Earth's rotation on its axis. As the Earth rotates, different parts of the sky come into view, causing the stars to move across our field of vision. The apparent motion is a result of the observer's perspective from the rotating Earth.
If there are clouds moving in the sky, this may provide the illusion of movement. Also, due to Earth's rotation, everything around us seems to turn around the Earth.
Since Earth's surface is rotating toward the east, "fixed" celestial bodies appear to be moving toward the west.
