NASA, after 8 years, still can’t tell what these geoglyphs really are! (VIDEO)

They are almost 8000 years old!

 

After more than eight years and NASA has yet to answer what these 260(!) geoglyphs in Northern Kazakhstan really are. They were discovered in 2007 and the satellite images draw the attention of experts on the field, including NASA that tried to find their origin.

 
Archaeologists argue that they are man-made but it is unknown why they were made. Their size is such that their shape can only be seen from great altitudes.

What is important though is that they are dated as approximately 8000 years old, which predates any known civilization.

Also, the area was a hunting ground for early men, but according to the scientists no tribe of humans stayed long enough to build these geoglyphs.
