Up until 2007, no one knew that these even existed, until NASA took some satellite images. Then they discovered this pattern, dating back 8,000 years. Experts are baffled, as the mounds are raised earth, which points to them being man-made.

Unfortunately Kazakhstan has no interest in investigating the discovery, so now, 10 years later, we still don’t know what these were. Some say it was a way to track the sun by the Neolithic people, while others suggest alien landing site.
