Scientists believe that the mystical disappearance of the first civilization is even more mysterious than it seemed at first glance.
The Harappan or Indian civilization appeared and developed a little earlier than two other great civilizations of that time, Ancient Egypt and Mesopotamia. The heyday (3300 - 1300 BC) allowed civilization to capture almost the entire Indian subcontinent. Then a sudden decline began - earlier scientists believed that it was associated with climatic changes, but now the erroneousness of this opinion has become clear.
It turned out that, unlike other ancient civilizations of Ancient Egypt and Mesopotamia, inextricably linked with three rivers, Nile, Tigris and Euphrates, the Indian civilization did not depend on waterways at all.
Moreover, on the territory of this civilization, scientists have discovered the decay products of uranium. It sounds fantastic, but there are already assumptions according to which the people of the Indus River had the appropriate technique.
