Perhaps the earliest and most important invention was the invention of fire.People probably first used fire started by lightning(閃電).Lightning would hit a tree in a forest and cause a large fire.People would use a small piece of burning wood from the fire to start their own-small fires.With these fires,they could cook food and keep warm.They could also see more easily at night of course,the piece of wood would soon stop burning,and they would not be able to create fire from it again.They had to find other ways to create fire.One way to create fire is by rubbing two pieces of wood together.This can take a lot of time and can be difficult,however.Another way is by hitting two rocks together.This can also take a lot of time and can be difficult.An easier way is by using a piece of glass and the light from the sun to start a fire.
