What have cataclysms to do with the history of civilization? More, much more, than we have ever been led to believe. Civilizations have come and gone more often due to cosmically induced cataclysms. Indeed the history of civilized mankind is much older than accepted by modern science and religion. And maybe the myth of anthropogenically generated climate change might have to viewed differently as I reveal that climate change caused by cosmic collision has been a greater influence on human culture throughout our known and previously unknown history.Throughout history myths and legends repeat the same themes of devastation from above as well as earth covering floods. Is there any hint of truth to these tales of destruction and carnage?Are myths and legends, including the stories in the Bible, actually eye-witness accounts of these periods of destruction?Are these periods of destruction actually repetitive like cycles and movements in a cosmic clock?What then of the destruction of legendary Atlantis or even Eden?Is there a grain of truth even for any of these legends?
