The worldwide Noahic Flood.
From the excerpt: “The remains date between 20,000 and 10,000 years in age.”
Long flood.
The flood story is in every prehistoric society all over the globe. Totally real event. Probably when the comet struck the Earth around 10-12k years ago and melted the polar ice caps.
Amazing when you think about it. Further proof of the historical basis of the bible.
True... evidence of this having occurred is all around us.
