Two hundred thousand years ago at least six species of humans inhabited the Earth. Today only one remains: us, Homo Sapiens. Our evolution has endowed us with self-awareness with which we started writing our story. Since the Paleolithic we have experienced a slow and constant technical and cultural development. To the manifestation of phenomena unknown to us, we found a device in the gods. Over the centuries we have created borders, stipulated laws and determined the value of our assets by giving a price. Al this has led us to be the society we are. The secret of our success is our imagination.
