My mother’s father told of a great war in the 1940s and what it was like to be blown off the deck of a battleship in Pearl Harbor on December 7, 1941. My father’s father would tell what it was like to be in the German Luftwaffe in Northern France during the late 1930s and labeled a traitor for criticizing Hitler in the 1940s in Germany during a great war. My father’s uncle would tell what it was like to fight and freeze in Russian and be captured and sent to Siberia in a great war in the 1940s. It was also told that another of my great uncles died in a battle outside Stalingrad in the 1940s. All these different stories told about a great worldwide war in the 1940s. Very different stories. It would be absurd, however, for me to conclude that these stories were false because they reported different events from a great war. It would be doubly absurd for me to conclude that these different stories indicate that in fact there was no great war.
Of course, that would be absurd if I was using such reasoning to disclaim that there was a historical cataclysmic worldwide war. If, however, I was using such reasoning to disclaim the existence of a historical, cataclysmic worldwide flood, I would be a respected academic. Steve Ham provides an excellent analysis on how ancient records to include The Gilgamesh Epic support the Scriptural history of the worldwide flood here. A telling well worth the reading.
