Hebrew University doctoral student, Ido Wachtel, helped in discovery of massive 5,000-year-old stone monument in Israel, near the Sea of Galilee. Initially, archeologists thought the structure was part of a city wall, but Wachtel’s latest work found there was no city near it. Wachtel states that the structure acted as a prominent landmark for a local community. Bigger than the size of an American football field, the structure predates the Egyptian pyramids and Stonehenge. Pottery found at the site suggests the structure dates between 3050 B.C.E and 2650 B.C.E.
