Karahunge - The secret of the Armenian Stonehenge

This Stonehenge like temple was built by the ancient armenians 7500 B.C. Nobody can explain how people carried the stones there. More info you find here: http://www.carahunge.com/

About 80 stones are round hole, although only about 50 survived of the stones. They are of interest to Russian and Armenian arheoastronomistiv who believe that they could be used for astronomical observations. This was caused by four holes, which indicate the point where the sun rises on the day of the summer and four others in a place where the sun sets on the same day.

In my opinion it is possible that extraterrestrials helped planning and building the complicated structure.
