Mysterious rock carvings in Xinjiang resemble airplane

Rock carvings discovered in Duogate cave in Habahe county, Northwest China's Xinjiang Uyghur autonomous region. Archeologists have discovered 893 rock carvings in about 20 sites around the county, with the earliest dating from around 10,000 years ago. Those petroglyphs were made at various points in time and cover a broad range of topics, such as hunting, herding, and ritual activities, and some may even resemble planes or rockets in the eyes of modern people.
