I may be wrong, but you seem to be proffering Noah's flood as an explanation for the apparent aged look of the rocks of the earth. I'm no scientist, but I know they dom more than just look at a rock and decide that it looks old. Water may account for wear and tear. However, it has nil effect on the decay of carbon 14 atomsin rocks that scientists use to date them. Your argument would hold water (pun excusable) if scientists were just looking at how old rock looks. Carbon 14 are carbon that have 14 neutrons.
You must have at least a rudimentary understanding of carbon dating before you decide scientists don't know what they're talking about.
Actually, carbon 14 has 8 neutrons. All carbon atoms have 6 protons. It is the presence of exactly 6 positively charged protons in the nucleus that is responsible for defining the electron configuration of the neutral carbon atom and from that the chemical properties of carbon atom. It is those specific chemical properties that make carbon carbon.
Different varieties of carbon atoms all have essentially the same chemical property, but their atomic nuclei have different masses. All atomic nuclei consist of some mixture of positively charge protons and neutral neutrons of very similar mass. All carbons have 6 protons, but those with mass 14 (ie carbon 14) have 14-6=8 neutrons, while the much more common (and non-radioactive) carbon 12 have 12-6=6 neutrons.

Intriguingly, that does not appear to always be true. Organic material has been recovered from Cambrian marine fossils preserved in very fine grained sedimentary rocks. Many of the fossils of soft bodied animal forms, as well as some hard shelled arthropods, were preserved as impressions in very fine grained marine sedimentary rocks. Many of these fossils have dark colored discoloration around them. It has been shown these discoloration are actually a very thin layer of carbon from the original soft tissues of the animals that oozed out of as the animal’s body was compacted by the sedimentary process.
So organic material definitely can and do survive fossilization. But much more stunning is fact that actual original soft tissue appeared to have survived inside some fossilized dinosaur bones. Some tyrannosaur femurs were found to have only fossilized part of the way through the bone. The interior of the bone was not only not mineralized, there were even what appeared to be extremely well preserved soft bone marrow tissue as well as blood vessels with blood cells inside in vasculated parts of the bone. Unfortunately this was only recognized part of the way through the conservation process, by which time the conservation process, while preserving the texture and form of the soft tissue remains, destroyed any possibility of DNA recovery.
However, there was never any possibility of carbon 14 dating because the dinosaur bones were simply too old for any meaningful analysis of carbon 14 to decay daughter element analysis.
Hair well and truly split.
