内容简介：
I wrote this book because the subject matter has always intrigued me. Iave always been fascinated by our exploration of outer space. But what is even more amazing to me is the amount of things on this earth that are unexplained. I also wanted to use mysteries that have longevity because these are the hardest to explain and are puzzling for the simple fact that they have endured for so long. I hope when you read this book you will look at all the different explanations and theories and keep an open mind. In many instances, believing in something is like having religious faith. To have belief without concrete proof is one of lifeas biggest challenges. I think once you pick this book up, it will pique your interest and youall get so engrossed you wonat be able to put it down. Enjoy your journey through the mysteries of our planet earth.
