Does the presence of marine fossils on mountain tops confirm that Noah's Deluge really happened?

Answer 1

No. Marine fossils are formed when marine creatures die and their bodies fall to the bottom of the sea, where they become covered in silt which eventually hardens into rock. If there ever was a great flood that could cover high mountains, any marine creatures that died would still fall to the bottom of the sea - not up to a mountain top. Nor would they form a scientifically correct geologically column on the mountain, with older species at the bottom of the column and more modern species at the top of the column.

The presence of marine fossils on a mountain top merely shows that the mountain is of recent origin, having been uplifted by geological forces perhaps only a few million years ago. Prior to the uplift, the mountain formed part of the sea bed.

Further, such a flood would not create fossils. Fossils most often form at the bottom of bodies of water were there is little oxygen and where they are repeatedly silted over and protected from mechanical damage. If a flood reached into the mountains, it certainly would not leave deep sediments there, so any marine creatures left behind would be eaten and scattered to the winds. And such fossils are found in SEDIMENTARY rock, usually formed when layers of silt are laid down again and again over many years until they are crushed into rock by the pressure. A biblical flood could not create such rock. At best, it might leave a few pools of mud that might hold a few skeletons--but again, these would not become entombed in sandstone, nor fossilized.
