Why Causes the sun to rise and set

The sun stays in its position at the center of our solar system. It doesn't rise and set. But it appears to rise and set because of the Earth's rotation on its axis. It makes one complete turn every 24 hours. It turns toward the east. As the Earth rotates toward the east, it looks like the sun is moving west. As the Earth rotates, different locations on Earth pass through the sun's light. As your town turns toward the sun and begins to enter its light, the sun seems to rise in the east. As your town begins to leave the sun's light and enter darkness, it appears to set in the west.

Since we are constantly rotating on earths axis it makes it seem as though there is a sun rise and a sun set
