Fire

Fire is a rapid oxidation procedure that creates light, heat, smoke, and releases energy in varying intensities. It is commonly used to explain either a fuel in a state of combustion or a violent, destructive and uncontrolled burning (e.g., in buildings or a wildfire). The discovery of how to make fire is considered one of humankind's most important advances, allowing higher hominids to ward off wild animals, cook food, and control their own source of light and warmth.
