This is an extended edition, revised and updated. It contains articles on ancient mechanisms and optics, the mysteries of the submerged continents and options for the appearance of the first people on Earth. Also here you will find an interesting article about Viking treasures.

In our age of advanced technology, it would seem, very soon, all the riddles of the world will find easy and correct answers to the questions that have tormented researchers for centuries. However, it is not. And with the growth of opportunities, the number of puzzles has also increased, many of which turned out to be high-quality fake and deception thanks to all the same capabilities. And archaeologists believe that the secrets of ancient civilizations are not so easy to unravel, and this may take even centuries.

In books that debunk "cult" archeology, explicitly or implicitly it is understood that no ancient secrets remain, that professionals are already in everything figured out and came to the final conclusions.

In this book we will touch on the secrets of ancient and modern history, which do not have a definite answer to the questions posed.
