The discovery of fire is one of the most important events in the history of humanity, since it has allowed us to evolve to what we are today and develop our intelligence. It is now known that Man discovered fire 790,000 years ago, despite previous research saying that Homo Erectus had learned to manipulate and use fire, but it was not known if he could truly create it or take it from other places - for example, natural phenomena. The discoverers of fire. How to find out if the Homo Erectus knew how to handle fire accurately? The answer seems to have been found at the Hebrew University of Jerusalem (Israel), by analyzing the fossil remains of populations found along the Jordan River. There they have found the necessary proofs to affirm that 790,000 years ago the Men had a high control of the fire. Although it is not very clear after the investigation how Homo Erectus used to generate it, it can be assumed from the remains that not all of its fires were generated from natural phenomena - like lightning - and then expanded - for example, through transportation of a branch lit. The site to be analyzed by the archaeologists includes 12 layers, and in all of them -which comprise a period of 100 thousand years of history in total- there are clear signs of the use of fire: metal tools, a prehistoric flint or charred wood, therefore, it is unlikely that all the peoples that existed in that period of time would have had access to a fire produced naturally. Fire and the advance of humanity. Man discovered fire 790000 years ago. The power to control the fire has allowed Men to have a certain independence, which in turn contributed to the migration from Africa to Europe, to then be able to expand throughout the world. This is because, being able to generate fire, the Men did not depend on the natural causes to be able to use it and they had greater facility to move without climatic concerns. With fire, Man has been able to protect himself against ferocious animals, cook and make tools and weapons; since fire is a symbol of light and heat. Having weapons with which to defend and illuminate during the nights allowed humans to feel less fear of the unknown, while the heat provided by this element allowed us to travel to cold places. Undoubtedly, fire was a great ally of Men during antiquity and to the present. In a way, fire has changed our ways - for example, we are the only animal that cooks its food, instead of eating it raw - and it has made us who we are.
