On Earth discovered huge wheels

Mysterious giant stone structures were discovered by scientists in the Middle East. Thousands of characters like the famous drawings of the Nazca in Peru, stretch from Syria to Saudi Arabia.
At the same time, be seen as a whole and to assess their scale is only possible from the air.
Ancient stone structures called geoglifi, were first discovered by new satellite technology in Jordan.
According to David Kennedy from the University of Western Australia, in Jordan they are more than the valley of Nazca.
"In addition, they cover a wide area and are obviously much bigger" - he said, noting that these geoglifi are at least 2,000 years.
All buildings have a common design in the form of a circle with spokes and are therefore called "wheels". However, the circles that have a diameter of 24 to 70 m, significantly different.

 
"Wheels" is composed of diamond structures, small stone pyramids and stone walls located chaotically.
Some facilities are independent, while others are grouped.
In addition, Saudi Arabia, the researchers found pentagonal structures and "Wheels" only two "spokes".
To determine the purpose of these facilities is difficult because none of them has not yet been excavated. Initially, scientists have suggested that they may be remnants of homes and cemeteries.
However, Kennedy is convinced that none of these explanations do not correspond to reality. "Perhaps, in this region, there was a cult in which it was necessary to create a circular design," says the scientist. Some "geoglifi" may be ancient cemetery, he said.
