Detailed explanation-1: -We see the sunrise and sunset because of Earth’s rotation about its own axis. Earth is rotating about its own axis from West to East. So, when seen from the Earth, the Sun appears to rise in the East and set in the West.
Detailed explanation-2: -At the fall equinox, the Sun rises due east and sets due west. It continues on it’s journey southward until, at the winter solstice, the Sun rises are far to the south as it ever does, and sets as far to the southwest. Many, if not most, prehistoric cultures tracked these rising and settings points with great detail.
Detailed explanation-3: -From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.
Detailed explanation-4: -Earth and most of the other planets rotate on their axis from West to East. So, to an observer on the Earth, Sun rises in the East and sets in the West. However, Venus rotates in the opposite direction, i.e., from East to West. So, on the planet Venus, Sun rises in the West and sets in the East.
Detailed explanation-5: -When viewed above the North Pole, the Earth rotates counterclockwise, from west to east. This is also called a prograde rotation. Because of this direction of rotation, we see the sun rising every day in the east and setting in the west.
