Truth is much stranger than fiction and this book is filled with facts and history... FORGOTTEN history. You can look up almost any fact in this book and find that it actually happened. The most impressive details are often subtle details. Every time you read it, you will find a new one. The book has many radically different ideas about Atlantis, Mars, UFO's, SETI, quantum physics, and even Bigfoot. There are introduction paragraphs at beginning of each chapter and a glossary at the end. The glossary is both helpful and functional. There are key bits of information you don't get from the story.
