implausible? FACE VALUE? Matthew 19:26 "But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible."
That is an appeal to faith and/or belief, not reason. The Bible doesn't offer any eevidence that any God exists, nor that any of the storeis are true in reality, so we dismiss any of it being interpreted literally by default.
Feel free to offer facts and a coherent explanation that any of your interpretations are true. Thus far you only refer to the Bible, which is the source of your claims, not evidence. You thinking the Bible proves itself is a alogical fallacy called circular reasoning.
So, since facts gathered in geology, archaeology, biology, genetics, cosmology, chemistry, and other sciences the claim that a global flood occurred in the near past isn't true or even plasible. I will add engineering because the claim of some massive wodden boat being built to the size the Noah myth suggests could not be built even today with modern techniques and technology. Wood does not have the strength to withstand the forces of water on a hull as it floats. The largest wooden ship ever built was the Wyoming and was 450 feet long and finished in 1909. As it sailed the sailoers reported constant twisting and creaks, and they had to put numerous pumps to remove the water because it constantly leaked. It ended up sinking in a storm. The Noah flood myth refers to a massive deluge and storm waters covering the earth.
Back in the late 90's a creationist engineer was dead set on examining all the woods on the planet and figuring out what gopher wood was, the wood the Bible claims the Ark was made from. He tested every wood he could find and reported the specifications and how well it would work buing use to build a wooden ship estimated to be 800 feet long and 60 feet wide. As he worked he discovered few wood were suitable to build a boat with, and eliminated each one. In the end he couldn't find any wood that could be used. His (bad) conclusion was that gopher wood was a pre-flood type that no longer exists. Did he have any evidence of this? No, it was the only conclusion he could dream up so he could maintain his assumption that the Noah myth was true. I tried to find his website some years ago and it was no longer there. I don't blame him, why advertise that your beliefs can't be supported by the facts?
That aside, it is the fact that there are settlements and civilizations that have gone on existing from well before the time of Noah that did not get interrupted by a global flood, namley in India and China who have records and long term established histories.
But the most devastating fact against a global flood is genetics. If there was a flood like that of the Noah myth there would be a genetic bottleneck of all species going back 4000 years or so. There isn't. This is a "nail in the coffin" to the Noah myth believers. This makes the myth impossible despite what any Bible text says.
