Explanation

If we could see the sun and stars simultaneously, then we would see that during the course of one day, the sun would be inside one constellation. because it is the rotation of the earth that causes the sun and stars to move across the sky . therefore we expect that sun and stars both move at the same rate. hence the sun will be seen inside of the same constellation during the entire day
