Even if that is the case how does that help the Noah's Ark myth?I point out ...There are other stories of a Great Flood other then in the bible! And.. The Sphinx (Lion) in Egypt archeologists say; the wear on it is believed to come from water!
And no, that does not appear to be the case at all:
Sphinx water erosion hypothesis - Wikipedia
The Sphinx water erosion hypothesis is a fringe claim, contending that the Great Sphinx of Giza and its enclose walls eroded primarily due to ancient floods or rainfalls, attributing their creation to Plato's lost civilization of Atlantis over 11,500 years ago.
Egyptologists, geologists and others have rejected the water erosion hypothesis and the idea of an older Sphinx, pointing to archaeological, climatological and geological evidence to the contrary.
