That isn't the dumbest question but it sure is the dumbest answer.
The seasons are not caused by the sun being colder on one side than the other.
They are caused by the tilt of that axis of the earth at about 22º which causes the intensity of the sun's rays, which are parallel, to b spread over greater or lesser areas of the earth's surface, resulting in absorption of less or more energy. Try the old school experiment of shining a torch vertically over a flat surface and then at an angle. The illuminated area is larger from an angle, spreading the given amount of light over a larger area.
