The motion was initiated almost 5 billion years ago,
as the gas cloud that formed the solar system compressed under gravity
it formed a spinning disk that imparted the motion of all the planets and the rotation of the sun.
If there had been no rotational motion (a possibility - low) there would have been no planets.
Earth's rotation on its axis causes day and night. Earth's revolution around the sun causes the seasons.
No, the Earth's revolution around the sun is not related to the rising and setting of the sun on a daily basis, which is caused by the Earth's rotation on its axis.
