About the book: 1998 / This book is about the great creations of human hands, erected at different times on different continents. They are not alike - the pyramids of Ancient Egypt and the majestic terraces of Baalbek, the idols of Easter Island and the megaliths of Stonehenge. But they have one thing in common: scientists still cannot finally decide who erected all this and when exactly. What guided the ancient architects when building such complex buildings as the pyramids? Who is the real “author” of the Egyptian pyramids? Did aliens from outer space have a hand in the construction of the terraces of Baalbek? Was Stonehenge an astronomical observatory for the ancient Celts? Who taught the stone idols of Easter Island to walk? These and other questions are discussed in the book.
