The New York Times recently published an article about evidence for a possible meteor impact
in the Indian Ocean that caused a mega-tsunami some 4500 years ago. Part of the evidence is what the investigators call "chevrons" of displaced earth near the shore in Madagasgar. These valleys are theorized to have been carved out by a 600 foot high tsunami. By examining the direction of the chevrons, the investigators have found solid evidence of a large impact crater at the bottom of the Indian Ocean. Further, silt deposits in the chevrons contain ocean-bottom minerals fused to deep water micro-fossils, which are characteristic of impact events.
Other researchers have correlated multiple flood myths with known astronomical events (a solar eclipse) and found agreement with the geological age data. Torrential rains, weeks of darkness (oh, say 40 days) and of course, tsunami floods would all have been coincident with such an event.
This is certainly a credible explanation of flood myths and end-of-days prophecies. Unfortunately for the Creationists and other holy-rollers it has nothing to do with the supernatural.
There go those scientists again, taking all the fun out of make-believe.
