Everything on earth is designed to function according to times and seasons. The sun, for instance, rises
from the east at a certain time of the day and it must of a necessity change direction, heading towards the west as the day progresses and then sets ultimately as it is designed to do. No matter the weather condition, raining, cloudy, snowy or sunny, the sun never stays static. It keeps moving whether we can see it or not, until it arrives at its predetermined course in the West.
