the earth rotates around its axis, causing sun up and sun down. (given) as it rotates the sun hits a different part of the earth, which gives us the view that the sun is moving. If the earth didnt rotate, half of the world would have day time for half of the year while the other side would be in the dark for half of the year, whick would affect growing seasons and many other things.
