Prologue: Genesis
 
"The Old Testament has filled my life from childhood. When the seed for this book was planted, nearly fifty years ago, I was totally unaware of the then raging Evolution versus Bible debates. But as a young schoolboy studying Genesis in its original Hebrew, I created a confrontation of my own. We were reading one day in Chapter VI that when God resolved to destroy Mankind by the Great Flood, "The sons of the deities", who married the daughters of men, were upon the Earth. The Hebrew original named them Nefilim; the teacher explained it meant "giants"; but I objected: didn't it 
mean literally "Those Who Were Cast Down", who had descended to Earth? I was reprimanded and told to 
accept the traditional interpretation. 

In the ensuing years, as I have learned the languages and history and archaeology of the ancient Near East, the Nefilim became an obsession. Archaeological finds and the deciphering of Sumerian, Babylonian, Assyrian, Hittite, Canaanite and other ancient texts and epic tales increasingly confirmed the accuracy of the biblical references to the kingdoms, cities, rulers, places, temples, trade routes, artifacts, tools and customs of antiquity. Is it not now time, therefore, to accept the word of these same ancient records regarding the Nefilim as visitors to Earth from the heavens? 

The Old Testament repeatedly asserted: "The throne of Yahweh is in heaven"-"from heaven did the Lord behold the Earth". The New Testament spoke of "our Father, which art in Heaven". But the credibility of the Bible was shaken by the advent and general acceptance of Evolution. If man evolved, then surely he could not have been created all at once by a deity who, premeditating, had suggested "Let us make Adam in our image and after our likeness". All the ancient peoples believed in gods who had descended to Earth from the heavens and who could at will soar heavenwards. But these tales were never given credibility, having been branded by scholars from the very beginning as myths. 

The writings of the ancient Near East, which include a profusion of astronomical texts, clearly speak of a planet from which these astronauts or "gods" had come. However, when scholars, fifty and one hundred years ago, deciphered and translated the ancient lists of celestial bodies, our astronomers were not yet aware of Pluto (which was only located in 1930). How then could they be expected to accept the evidence of yet one more member of our solar system? But now that we too, like the ancients, are aware of the planets beyond Saturn, why not accept that ancient evidence for the existence of the Twelfth Planet? 

As we ourselves venture into space, a fresh look and an acceptance of the ancient scriptures is more than timely. Now that astronauts have landed on the Moon, and unmanned spacecraft explore other planets, it is no longer impossible to believe that a civilization on another planet more advanced than ours was capable of landing its astronauts on the planet Earth some time in the past. 

Indeed, a number of popular writers have speculated that ancient artifacts such as the pyramids and giant stone sculptures must have been fashioned by advanced visitors from another planet-for surely primitive man could not have possessed by himself the required technology? How was it, for another example, that the civilization of Sumer seemed to flower so suddenly nearly 6,000 years ago without a precursor? But since these writers usually fail to show when, how and, above all, from where such ancient astronauts did come-their intriguing questions remain unanswered speculations. 

It has taken thirty years of research, of going back to the ancient sources, of accepting them literally, to re-create in my own mind a continuous and plausible scenario of prehistoric events. The Twelfth Planet, therefore, seeks to provide the reader with a narrative giving answers to the specific questions of When, How, and Why and Wherefrom.  
The evidence I adduce consists primarily of the ancient texts and pictures themselves.  
In The Twelfth Planet I have sought to decipher a sophisticated cosmogony which explains, perhaps as well as modern scientific theories, how the solar system could have been formed, an invading planet caught into solar orbit, and Earth and other parts of the solar system brought into being. 

The evidence I offer includes celestial maps dealing with space flight to Earth from that Planet, the Twelfth. Then, in sequence, follow the dramatic establishment of the first settlements on Earth by the Nefilim: their leaders were named; their relationships, loves, jealousies, achievements and struggles described; the nature of their "immortality" explained.  
Above all, The Twelfth Planet aims to trace the momentous events that led to the creation of Man, and the advanced methods by which this was accomplished. 

It then suggests the tangled relationship between Man and his lords, and throws fresh light on the meaning of the events in the Garden of Eden, of the Tower of Babel, of the great Flood. Finally, man - endowed by his makers biologically and materially - ends up crowding his gods off the Earth. This book suggests that we are not alone in our solar system. Yet it may enhance rather than diminish the faith in a universal Almighty. For, if the Nefilim created Man on Earth, they may have only been fulfilling a vaster Master Plan.
