“Our ancient worlds continue to be a mystery, but there is a lot of evidence to suggest that they were far more advanced than we were, and that they might have had some help.” – A Walia

A lunar crescent shaped stone monument has recently been discovered in Israel. It dates back approximately 5000 years, between 3050 B.C. and 2650 B.C., which means it is most likely older than the pyramids of Egypt, and built before the Stonehenge was constructed.
It’s located approximately 8 miles northwest of the Sea of Galilee, and is massive. It measures approximately 14,000 meters, which is about 500,000 cubic feet.
Ido Wachtel, a Doctoral student at the Hebrew University of Jerusalem said:
“The proposed interpretation for the site is that it constituted a prominent landmark in its natural landscape, serving to mark possession and to assert authority and rights over natural resources by a local rural or pastoral population.” (source)
Again ,the structure is about 150 meters (492 feet) long and 20 m (66 feet) wide at its base. According to Wachtel:
“The estimation of working days invested in the construction [of] the site is between 35,000 days in the lower estimate [and] 50,000 in the higher.” (source)
