The author, while living in Portugal came in contact with a book describing the events in Fatima, such as the display on the sky which was witnessed by 50,000 people. As a physicist, specialising in lasers, he came to the conclusion that these events were neither of natural nor divine origins, but they had to be prepared by beings of much higher than human intelligence. Following this hypothesis he arrived at a logical conclusion that the intelligent beings had intervened in human affairs from the very beginning of homo sapiens on Earth. His book explains many mystifying events in the history of mankind such as the origins of the first civilisations and the arising of the main religions. Certain events in the 20th century such as the fall of Nazism and communism are elucidated using this approach. The book tries to answer questions: Why the intelligent beings are interfering in human affairs? What are their objectives? and provides an answer to such a timeless question as: "What is the purpose of human life?"
