It is not warm........... it is STEAMING HOT! It is so hot because we need warmth. Some people like it because it gives them a tan. The sun also has vitamins in it. So, the sun is good for our skin also. We need warmth because we can not stand the cold! We will get sick! We would probably be sick for the rest of our lives if it was not for the sun. Same for the animals too!
The sun is hot because the atoms deep inside the sun are undergoing nuclear fusion. Nuclear fusion releases a lot of energy. This energy excites all the other atoms in the sun, and causes them to move about. This is what heat is. So the nuclear reactions inside the sun cause the sun to be hot.
