Before World War I and II was an even more devastating war that changed humanity forever. Instead of 3 percent of the population of the world dying, 1/3 of the populations of the world were gone. Massive destruction around the planet. Hundreds of millions that remained suffered from sickness, mutation, loss of country and even loss of self as humanity was thrust into a Stone Age existence 55 hundred years ago. Melted walls and radioactive skeletons tell of the destruction and historical references of horrible weapons can be found everywhere. Entire populations moved underground to survive. This book describes the evidence, cause, effect, and devastation of this almost forgotten World War before World War I. I call it World War Zero.
