If Gorbachev Had the Mark of Cain, Did He Too Buy a Condo in Qatar?

Cain was said to go East of Eden to the Land of Nod. Nod means fugitive/wanderer in Hebrew. He is believed to have founded the first city and started a family there. The implication is heavy that people were already living there. He was given the mark of Cain so no one would take revenge upon him in his travels. If Eden was perhaps somewhere in Saudi, Cain may have journeyed to found a city that presently is 200 feet or more below Sea level of the Persian Gulf. The time era for that crime and punishment could have been the Younger Dryas.
