Where to look for the legendary Atlantis? Where did the Khazar kingdom disappear to? Why did the mammoths die? You will not find answers to these questions in the book in front of you. And not because there are none, but because there are too many of them. The reader is invited to decide for himself which of them is the most correct. A lot of quill pens, ballpoint pens, and printer cartridges have been spent in search of the truth about disappeared civilizations, the Bermuda Triangle, and flying saucers. In this book, such breathtaking topics are examined from new perspectives of the latest achievements of science.
