Eight thousand years ago, someone or something decided to construct hundreds of massive geoglyphs right into the side of the Kazakh Steppe in northern Kazakhstan. Some believe that tribespeople who used to roam the area are responsible.
That claim, if true, would challenge everything scientists know about early humans. Might a more extraterrestrial explanation be necessary?
To find out more about these geoglyphs, researchers have enlisted the help of NASA.
NASA has discovered over 260 geoglyphs in this area.
Just to give you an idea of how big these formations are, the largest one on record covers more than 810,000 square feet.
Despite their expertise, researchers still have no idea who (or what) made them. While it's certainly possible that early hunter-gatherers built them, this explanation challenges everything we thought we knew about early humans.
"The idea that foragers could amass the numbers of people necessary to undertake large-scale projects -- like creating the Kazakhstan geoglyphs -- has caused archaeologists to deeply rethink the nature and timing of sophisticated, large-scale human organization as one that predates settled and civilized societies," said University of Winnipeg archaeologist Persis B. Clarkson.

It would seem that the origin of these ancient geoglyphs is a mystery wrapped in an enigma, as Dr. Who might say. Of course, you probably know what my take on the whole thing is...and it has to do with aliens.
