Scientists came to the conclusion that India civilization was preceded by ancient Egypt and Mesopotamia, and was based on 2,5 thousand earlier than expected.
A team of scientists analyzed the fragments of pottery and animal remains that have been found in India, we came to the conclusion that India civilization was based on 2,500 years earlier than expected.
This means that it is preceded by a time of existence of ancient Egypt and Mesopotamia. That is the conclusion, scientists have come through the method of radiocarbon and optical dating, which allowed establishing the fact that climate change, once considered the main cause of the decline of Indian civilization, only indirectly contributed to its destruction.
And the main reason could be the increase in the proportion of the rural population and the decline of cities.
