This is a very complex book that covers the history of Europeans from before the Great Flood (which followed the abrupt end of the ice age) to the misunderstood parts of history of the Phoenicians, Skyts, Goths, Mongols and others. As the title implies, the book begins with reasons for ice ages and climate changes, the Great Flood that followed the last ice age, and the animal extinction created by the Great Flood waters. The Great Flood was created by the melting of glaciers, and there is plenty of evidence of it in the book. Etymology is used extensively to show the formation of European languages and in order to prove certain historical facts. This book is written only for the best intellects. The language used is written as simply as possible in order to make the subjects well-understood.
