Images similar to this are easy to find by the thousands. Major buildings partially buried all over the world. Then the survivors recovered by utilizing the parts of buildings that remained above ground. They leveled it all and put streets, sidewalks, etc., on top of the mud. Later, people excavating to do new construction ran/run across the major parts of the buildings that were buried by mud. This is just too, too complicated for the ignorant, those too lazy to even look, and too possessed by mass formation history psychosis to even think of going against the unwashed mob.
Come at me. Explain the image, slick.
Still waiting. Behold the field where grows your arguments.
