"Ancient Aryan civilization achieved incredible technological progress 40 centuries ago
The Arkaim valley in the south of Ural was supposed to be flooded in 1987: local authorities were going to create a water reservoir there to irrigate droughty fields. However, scientists found strange circles in the center of the valley: the authorities gave archaeologists 12 months to explore the area. Scientists were shocked to find out that Arkaim was the same age as Egypt and Babylon, and a little older than Troy and Rome.
Archaeological excavations showed that the people, who inhabited Arkaim, represented one of the most ancient Indo-European civilizations, particularly the branch, which is referred to as the Aryan culture. Arkaim turned out to be not only a town, but also a temple and an astronomic observatory."
"The 17th century date suggests that the settlement was about co-eval to, or just post-dating, the Indo-Aryan migration into South Asia and Mesopotamia (the Gandhara grave culture appearing in the Northern Pakistan from ca. 1600 BC, the Indo-European Mitanni rulers reached Anatolia before 1500 BC, both roughly 3,000 km removed from the Sintashta-Petrovka area), and that it was either an early Iranian culture, or an unknown branch of Indo-Iranian that did not survive into historical times."
