According to my world-wide research there was an earthquake in the Dead Sea area about 2250 BC. The atmospheric records indicate very high spikes in the atmospheric record given by the Arctic ice cores of ammonia and sulphur dioxide molecules. These are taken to have been sourced from a prolonged crude oil and natural gas conflagration over a few decades that resulted in a world wide blanket of the Sun, cold, drought, starvation. Empires collapsed in Europe, China, India, the Americas. There was cannibalism in Sudan and the Nile delta. The Nile pretty well dried up. Indian rivers eventually changed course when the climate normalised.
I can go on for 25,000 words giving detailed support.
Think for a moment -- there are enormous reserves of oil and gas in the Gulf states. Comparable reservoirs are being exploited in the western Sahara. There is only a mere trickle in Israel, Jordan etc.
Yet a virtually continuous deep sub-strata of limestone reservoir exists from Kirkuk to Algeria with a big dry gap in the middle.
So the Chaldean civilisation died of starvation, so did their language. Q.E.D.
Something is not right. This message is just to keep things from messing up down the road
