We are accustomed to believing that ancient people were savages and had only rudimentary knowledge of the world around them. However, more and more new archaeological finds, more and more new information about the past, carefully analyzed by scientists, convincingly prove that the science of the ancients was at such a high level that, even using modern technology, it is sometimes impossible to repeat many of their achievements. Christopher Knight, international best-selling author "The Key of Hiram" and "The Second Messiah" and journalist Athan Butler conducted a sensational scientific investigation proving that the ancient megalithic system of measures was much more harmonious and balanced than modern systems, which in many ways continue to rely on it. The fact that the megalithic yard used in the construction of Cyclopean structures was reproduced by the ancient builders to the accuracy of the thickness of a human hair inevitably raised the question for the authors of this book about how the “savages” were able to develop and universally observe this universal measure of length. And he inevitably forced them to assume that there once existed a global and developed “Civilization No. 1” on Earth, information about which was deliberately “erased” by someone from the history of mankind.
