The society throughout the times suffered a gradual process from transformations that they had lead the man of the primitive to technological, of the nomad to the social one and at last of the caves to the space trips. All this evolution, would not be possible without the constant perfectioning of the genius human being, as for the domain of more diverse technologies gifts at each time, as example, and to ours to see the most important step of the humanity, the domain of the fire.
