We did not find only one thing - traces of a developed civilization. In general, there are no traces of a developed, in our understanding, society. Yes, we found stone arrowheads and darts, there are fish hooks, stone hammers and choppers. There are even very high-quality polished stone balls of incomprehensible purpose and even more mysterious stone disks, especially strongly captivating by the fact that even museum keepers do not know how they were made and what they were used for. We have seen the discs more than once. And yet this is not enough. There are no traces of buildings, walls, statues, roads - nothing that would indicate the remains of a full-fledged city.
