When did the first man appear on Earth? What did our ancestors eat until they "invented" french fries? How were the pyramids built and who erected the menhirs? Who invented fire and writing? What time did the Incas and Egyptians live? Archaeology is the science that studies the historical past of humanity. Archaeologists are interested in everything: an insignificant oil is a small fragment of an object, a simple observation of its location in the ground. And every find discovered by an archaeological expedition anywhere in the world fits into the page of a huge book whose name is Human History. The book tells about the organization of expeditions to search for archaeological sites, archaeological excavations, restoration of cultural monuments.
