Looking for physical causes of events described in the Bible beats the ass of rejection in toto.
But the embarassing thing - from my point of view - is watching otherwise intelligent people grasping at straws.
"Look, there was a tsunami! Must be the basis for the Noachian flood legends."
"Look, the glaciers melted! Must be the basis for the Noachian flood legends."
"Look, the Straights of Gibraltar opened up! Must be the basis for the Noachian flood legends."
I mean, why not just look at things in and of themselves? Theres really no way to tell, thousands of years after the fact, what people "might" have thought about anything at the time. If they didn't write an idea down, it's gone forever.
Yes, tsunamis happen, glaciers melt, lakes flood, and so forth. I would love so much to read about real historical events without the obligatory nod to Noah or Atlantis or any other fairy tale.
