Egypt and Sumeria are not the oldest civilizations. Exodus did occur. The Persians at the time (of Cyrus the Great) were Zoroastrians which is a monotheistic religion which no doubt influenced the Hebrews as did Babylonian beliefs. Mainstream science including archeology and physics are locked into their dogmas just like religions are. Exodus is supported by suppressed archeology and a better description of astrophysics is revealed by Steve Crouthers, Theoria Apophasis- AKA Ken L.Wheeler, and the Thunderbolt Project. Everything we've been taught is a lie.
