Let me also say that I have read all of Sitchin's books and found most, the first 3 or 4 at least, to be fascinating. I anxiously awaited this "Enki" book, because it was billed as a narrative that would fill in a lot of the gaps and answer a lot of my questions. It failed. It is written in a poetic style that is tedious and irritating; the reverse sentence structure in particular (think Yoda).
Rather than give any depth, insight, or fill in the gaps, it glosses over things are if they are a given. The ME for example. Mainly it just puts the story and information we already know from Sitchin's previous books in another format.
Rather than rehash all of his existing theories and information, I would hope that Sitchin would move on to explore other areas or at least uncover new info on his existing subjects. He could look into the manifestations of God in the Koran or Christian sacred texts, for example.
Something a lot of the reviewers/readers seem to be confused about: this is a hypothetical story; Sitchins idea of how it might have happened. Hello! The book makes that clear in the introduction. This is the Anunnaki story written AS IF it were translated from ancient Sumerian tablets, not translated from actual ancient Sumerian tablets.
One thing that I have always wondered about and that I hoped this book would adequately address is how Nibiru survives a long eliptical orbit around the sun. This books seems to explain it away by saying that Nibiru has a dense atmosphere which protects it from the variations in solar intensity that such an orbit would cause. We know that even the change of of a fraction of a degree can have major effects on the earth's climate. It is hard to believe that life could survive on Nibiru as it is defined. There may be some good explanation for this, but I have yet to read one.
Where did we come from? How long ago? This book is a good start to answering some of those questions. It makes me wonder why archaeology hides what goes against the current view instead of giving us all the information and letting us decide for ourselves. If you read this book with an open mind you will come away with much knowledge. As with anything take what vibrates with you and leave the rest. That doesn't mean it's not right but not right for you at the moment. Do I agree with everything Sitchin has translated - No, but never say never as I have had to eat those words along my journey. If you don't buy into the main stream view of how we got here and how long we have been here you will really enjoy this book.
Sitchin only goes back into time approximately 450,000 years. If you want to go back even further I suggest you read A Master's Reflection on the History of Humanity, Part I: Human Civilization, Origins and Evolution by Ramtha. Be prepared to have your mind expanded and answers to questions such as Who are we? Where did we come from? Why are we here? If you saw the movie "What the Bleep" you will love this book. Knowledge is power!
