The real occurrence of tsunamis can only be proved by empirical evidences; but as the proposed ones are representative of the most favorable scenarios for the hypothesis to be tested, the lack of any noticeable flooding, and the particular time sequence of water elevations, make difficult to accept them as plausible and literally explanation for the first plague and for the drowning of the Egyptian army in the surroundings of the Shi-Hor Lagoon, although they might have been a source of inspiration for the Biblical narrative.
That’s one reason that the Mysterious Universe article on Nazi zombies was depressing. The author writes that the trope of Nazi zombies may have emerged from a misunderstood passage in Life magazine reporting on the sarcophagi of Frederick the Great, Hindenburg, and Hitler found in Thuringia, sepulchers prepared as shrines for a future Reich. Life wrote that “The corpses were to be concealed until some future movement when their reappearance could be timed by resurgent Nazis to fire another German generation to rise and conquer again.” MU’s Brent Swancer, paraphrasing a Salon article, says that this could be interpreted as preparations for the resurrection of the dead in a literal sense. I guess that would make sense if you weren’t familiar with the Germanic myth of the Sleeping King, most famously told of Arthur the Once and Future King, but applied in Germany to Charlemagne, Frederick Barbarossa, and many others. Likely originally told of Odin, the myth held that the great Germanic hero was not dead but sleeping and would wake to save Germany at the moment of its greatest need. Hitler was using that myth, but that doesn’t mean he was literally building zombie army.
