Three world mysteries that challenge history and archaeology

We start off with the Mosaic lines of China, these strange lines are located at the coordinates 40 ° 27’28 .56 “N, 93 ° 23’34 .42” E. Information regarding these mysterious lines is very limited and the lack of scientific study has caused these mysterious shapes to become forgotten. The beautiful shapes are carved into the arid desert of the Chinese province of Gansu Shenp.
Just like the mysterious Nazca lines, it seems that these patterns were made to be seen from the sky. Some believe that these are fairly new lines and were created in 2004, but there is very little information about them.
The mysterious patterns of the Gansu Sheng region are located in the vicinity of the Mogao Caves, which is considered to be a World Heritage Site.

The unexplained Nampa doll is one of the out-of-place artifacts that seem to challenge history and everything we have been told in school.
The strange doll was discovered in 1889 in Nampa Idaho. It is a small figure that was excavated by accident during an oil drilling operation in the region.
The mysterious item has caused great interest in the past century since it is clearly made by human beings. The figurine was discovered at a depth of 320 feet which according to analysis would place the figurine way before humans arrived at this part of the world.
According to researchers, the strata at this depth is dated at about 2 million years old.
The figurine is composed of quartz and clay.
Due to the passage of time, the figurine is in very bad shape today. It has a circular shaped head, and its eyes and mouth are barely discernible, the right leg of the doll is broken. According to researchers, the Nampa figurine has strange geometric markings on its surface that are barely visible.
The First stone calendar, not far from the Great Pyramids of Egypt.

Among the many mysteries the Sahara desert has, there is one that in particular that has caused a lot of interest among archaeologists.
According to research, the Nabta playa stones are the oldest known astronomically aligned stones in the world.
Over a thousand years before the creation of Stonehenge, people created a stone circle and other structures on the shore of a lake that has long since dried. Over 6,000 years ago, stone slabs approximately three meters in height were dragged over a kilometer to create this incredible archaeological site.
Archaeological findings indicate human occupation in the region dating back to somewhere from the 10th to 8th millennium BC. Many argue that it’s very likely that hidden beneath the sand are more secrets that belong to the enigmatic history of this fascinating archaeological site.
