Once in a while, lightning started fires. Early humans saw the
fire and were afraid. They saw the animals run in fear. But
one day they didn't run away. Maybe they felt the heat on a
cold day. Maybe they noticed they could see at night because
of the fire.
No one knows how it happened. One brave person carried a
burning branch to a cave. People put wood on the fire to keep
it going. The fire kept them warm. It gave them light. It kept
dangerous animals away.
For the first time, they had a home. They no longer slept
wherever they were at the end of the day. The hunters came
home at night to their fire and safety. The children and the
old ones made sure the fire did not go out.
These early cave dwellers didn't know how to start a fire. If
the fire went out, they had to wait until lightning struck
again. Keeping the fire going was a very important job. They
had the first energy source that they could control.
