Fire is a discovery rather than an invention. Man had been searching since prehistoric times for a way of making fire easily and quickly, but a really satisfactory answer was found only when tinder-boxes and matches appeared on the scene.
Prehistoric men knew about fire. They must have discovered it by chance, perhaps when lightening caused a fire or when the sun, shining on dry leaves, caused them to ignite. To our ancestors, the discovery of fire was a important as the discovery of electricity or atomic energy has been to us. It was so important that to the primitive mind of early man it seemed holy, a gift from the gods, and become the subject of many myths. In ancient mythology fire worship reappears often.
One of the ways in which prehistoric men made fire was by rubbing two pieces of wood together. It could also be done by rubbing two flint stones together.
Once man has discovered fire, he could warm himself in front of the flames and cook the flesh of animals (previously he had eaten meat raw). Fire bought light into the dark caves. As time went by and men lived in houses, a fire in the hearth helped to create a homely atmosphere.
With the aid of fire, men could build furnaces into which they put iron or a variety of other substances, mixed with charcoal. they used bellows to make the fires hotter and so were able to fashion tools for many purposes.
For many centuries man used fire to help him with the task of everyday life, although he did not learn to control it completely until the invention of fuel ignition systems, without which modern industry could not function.
Thanks to fire, was able to manufacture files, saws, axes, hammer, anvils, tongs and deadly weapons. He also learned how to make glass. So the discovery of fire was of vital importance in the history of humanity. But such a powerful element has its dangers as well as its advantages. It can do us a great deal of good but can also bring disaster. Think of example of how we heat our buildings: they are comfortable to live in, but if something goes wrong a fire can break out and cause great destruction.
