First - "The practical upper limit on radiocarbon dating is about 50,000 years, because so little C-14 remains after almost 9 half-lives that it may be hard to detect and obtain an accurate reading, regardless of the size of the sample. ."
Not 5000 years.
But cosmic radiation goes through ebbs depending on magnetic fields, the sun and other factors, there are always events like supernova causing cosmic radiation to hit Earth.
How you think this even matters is a mystery? Besides that the radiocarbon dating is accurate even if it wasn't all of the geological markers for a worldwide flood say no flood. Your evidence is a fictive story. It does not matter if we did not understand how all animals ended up in a permafrost? We know it did not happen because an ice God waved a wand and made it happen or from a magic God-induced flood. These are myths.
Uh, permafrost is ground frozen for at least 2 years. So, ya, after a thaw more animals could die and become frozen. That actually completely debunks that entire line of argument.
Well as we see thawing permafrost is frequent enough to cause immediate harm to humans nearby:
"Thawing permafrost can have dramatic impacts on our planet and the things living on it. For example:
- Many northern villages are built on permafrost. When permafrost is frozen, it’s harder than concrete. However, thawing permafrost can destroy houses, roads and other infrastructure.
- When permafrost is frozen, plant material in the soil—called organic carbon—can’t decompose, or rot away. As permafrost thaws, microbes begin decomposing this material. This process releases greenhouse gases like carbon dioxide and methane to the atmosphere.
- When permafrost thaws, so do ancient bacteria and viruses in the ice and soil. These newly-unfrozen microbes could make humans and animals very sick. Scientists have discovered microbes more than 400,000 years old in thawed permafrost.
What Is Permafrost?
Since permafrost obviously can thaw and any animal can die and become frozen when it freezes over this isn't a mystery. However, even if it were a total mystery this doesn't make a mythic flood any more possible. It would simply be a reason we don't yet know.
Floods are ruled out. Frozen animals do not trump a long list of geological proofs of no worldwide flood.
There already is an explanation for side canyons, smaller rivers.

Again, without even looking into where the sediment is, an unanswered question in science does not mean one can import obvious myths as the answer. I could say the World Serpent eats sediment and that explains it and proves the serpent was real.
No, not one thing you have presented is evidence for a flood. They are evidences of things not yet understood or evidence of permafrost thawing, side rivers, human ship builders already knowing 3 ratios...
There is no such thing as a secular scientist. Scientists follow evidence as presented. If something is unknown then they simply say it's unknown. If something looks like it could possible be related to a supernatural event, they say "wow look at this interesting mystery!"
That is very rare. But they have tried. Years of studying remote viewing, random generators and conscious effecting outcomes, ll types of experiments. Dean radin talks about many of them. Ultimately they cannot be re-produced by outside teams which is the next step.
Now Biblical myths, no, do we study for evidence of Krishna or Zeus? I don't even know if you know what you are saying here? As science progresses most of these "I don't know" become known.
If you just said "God magic did it" then you stop learning. But you do have to study the magic? So where is that? are you fine with medical science? Because fundamentalists centuries ago would rather we just stick with prayer. Should our medical field be prayer? Or should we work with what we have - people, drugs, procedures, illness, pathology, technology? Why should any other science be different?
Would you expect a team of scientists who found a large hole in India to start arguing over if this was caused by the power of Krishna, Shakti, or was it Brahman? Each had their own theory. You would want them to investigate it from a geologist framework.
Your myths are no different or in any way special. They are borrowed stories from Mesopotamia. There have been thousands of Gods, every natural discovery could have been an action from one of these Gods? So should we endlessly speculate on which possible magic could have caused this or should scientists continue to work with the natural world and make incredible, yearly progress in every field?
Meanwhile the realm of magic, sorcerors and Gods has produced no actual evidence to test or even confirm it's existence.
Also archeologists have shown places and events in the OT are usually much exagerrated, enlarged or didn't likely happen.
JOSEPH CAMPBELL: Well, the cutting up and burial and then growing of the plant world, the world of the plant that you eat being already a cut up dead body, is the dominant motif, I would say, in the most of the tales. It occurs all over the place, particularly in the Pacific cultures and in the Americas.
BILL MOYERS: Tell me that story of the origin of maize, as Longfellow borrowed it from the Chippewas, didn’t he, or the Algonquins?
JOSEPH CAMPBELL: Well, it’s an Algonquian story, and it is simply of the boy in his vision, he sees a young man come to him with plumes on his head, and green and so forth, and visitant invites the young man to a wrestling match, and allows him to win. He wins and wins, this happens three or four times; but he tells him, “The last time I come, you must kill me and bury me, and take care of the place where you will have buried me.” And the boy then in the last one actually does what he has been told to do, plants the man, the visitant, and in time comes back and sees the com growing. And it was a boy who had been concerned for his father, who was a hunter but old, and he was thinking, isn’t there some other way to get food besides this one. And so it came to him out of his intentions. A lovely story.

"it occurs all over the place, particularly in the Pacific cultures and in the Americas."
There is no other evidence and 3 ratios is not evidence. In 1000 BCE the Egyptians and Persians were master ship builders and had incredible navys. The Israelites came from Canaan but before that they were Egyptians. Ship building knowledge was around and not at all proof of a message from a God. It's only evidence of one thing - religious syncretism, borrowing of stories from older societies and incorporating it into your own religion.
