To this day, scientists cannot solve all the mysteries of human civilization, writes RIA Novosti.

 Findings, which are found in different places on Earth show that many nations have simply disappeared, as if they did not exist. Despite the development of some civilizations, there is nothing left of them, except for the material artifacts.

Huge stone jugs were recently discovered in the jungles of India. Who made them and why - is unknown. Perhaps these are important ritual objects, similar ones were found in Indonesia. But we do not know anything about their creators.

Near the border between India and Pakistan at the beginning of the twentieth century was discovered an ancient city, huge and well-organized. The people had a full-fledged civilization, there is plenty of material evidence. And not a single trace of man himself. No burials, no bones.

In the east of Turkey, an unknown people built a giant temple, and it was at a time when they did not yet know how to cultivate the land or make clay - we are talking about the Stone Age. A huge temple complex was built, but who and to whom prayed in it is still impossible to understand.
