light:How did Man make light?

How did Man make light?

 One of the biggest achievements of Mankind was when our ancestors learnt how to make fire in the distant past. Early Man depended on the Sun for light during the day, and on fire for light at night. Later, people learnt that by rubbing two stones or two pieces of wood together, they could produce a spark. This discovery proved to be a turning point in the history of mankind, for it provided early Man with the knowledge to start a fire that would provide him with light, warmth, and safety from wild animals.
