Answer 1

Fire was first discovered by early humans. The method has not been found out. It can be assumed that it happened when two flint stones were rubbed against each other accidentally. Fire was useful to the early humans in the following ways:
1. Fire provided heat and warmth.
2. It was used as a source of light.
3. The early humans kept a fire lighted at the entrance of their caves in order to scare away wild animals.
