While I have liked Velikovsky since I first read several of his books about 35 years ago, I by no means believe everything he says. We will no doubt see how long the Dead Sea has actually been there once they start counting the layers (varves) laid down each year by the annual rainfall cycles. Also, I am wondering whether there could have been any catastrophic flooding caused by the sudden influx of the Atlantic Ocean into The Mediterranean once the Pillars of Hercules were breached by post glacial sea level rise. Also, as you have pointed out, there appears to be a 2 mile diameter boloid strike in the Iraq marshes from 4,000 years ago. Perhaps there has been a significant boloid strike in the Mediterranean which could have flooded the Dead Sea. How high is the lowest terrain between the Mediterranean and the Dead Sea? A catastrophe of that sort would certainly be visible in drilling cores. Can’t wait to see the results of drilling.
The Dead Sea is separated from the Med and from the Red by ridgelines approximately 600 m tall (I think that info’s in the V piece, I just didn’t quote it, other than citing it from my fallible memory). So, IOW, that would be a big splash. :’) Also, boloid strikes on the oceans IMO are the mechanism for glaciation in the first place, with tsunamis being a pretty minor sideshow.
