The earth spins on an axis which cause seasons. Those seasons can affect temperature in humans. The surface temperature of the earth from the sun causes humans a will to survive. As the earth rotates, one hemisphere will be day as the other hemisphere is night. That is caused by that rotation. For the earth to spin and the sun to shine keeping it warm, other loving things will survive on the planet too. With that, people can hunt the animals for food. The warmth on the earth can have plants growing on it to create oxygen from carbon dioxide that humans and animals breathe out. The animals and humans breathe in the oxygen. There are many more things on earth to keep loving organisms alive, but for this particular reason, this is what happens when the earth rotates and how it effects our everyday life.
