Put on your tin-foil hats and special anti-Illuminati underwear. A recently discovered mysterious ancient rock structure under the Sea of Galilee, possibly built in the same era as Stonehenge, has archaeologists stumped. To a certain slice of the population, any unexplained man-made rock pile is clearly evidence of an extraterrestrial visit.
Before we get too carried away, let's look at the actual data. The researchers, from Ben-Gurion University, Tel Aviv University, University of Haifa and Israel Oceanographic and Limnological Research, all in Israel, describe the cairn as a cone of unhewn basalt rocks, measuring approximately 70 meters in diameter and 10 meters tall. The site itself rests near a now-defunct ancient outlet of the Jordan River, an area that has had economic importance in the area since the Bronze Age. Due to various contextual details, the researchers suspect that the cairn was constructed sometime between the 4th and 3rd centuries BCE. Their findings were published in a recent issue of the International Journal of Nautical Archaeology.
