For years, Sierra has been working with people like Graham Hancock and Robert Bauval studying the existence of a Golden Age of the Humanity, dated in our most remote past. His hypothesis holds that this Golden Age was extinguished about 10,500 years ago, and it was the origin of all the known civilizations.
From an early age he was fascinated by the world of communications, conducting his first radio program in Radio Heraldo at the age of twelve. By the time he was sixteen, he was writing articles for the press, and at eighteen he was one of the founders of the international magazine A o Cero (Year Zero). At the age of twenty-seven, he became editor of the well-known Spanish monthly magazine M s All de la Ciencia.
