Mesopotamian records from about 2000 BC detail a major change in governmental procedure when invaders came into the region from all sides. They destroyed the temples the great multi-leveled ziggurats and introduced so many new languages that the whole of Sumerian culture fell into chaos.
Bodies dissolve like fat in the sun.
Our temple is destroyed. Smoke lies on our cities like a shroud. The Gods have abandoned us like migrating birds. Chronologically this ties in precisely with the Bible story of the destruction of the Tower of Babel and the resultant confusion of tongues. The whole story of this invasion and the departure of the Anunnaki is told at length in the clay tablets of Sumer and the net result was that the original divine Star Fire was no longer available.
