I’m not sure I follow what you mean here, but I presume you are insisting that the flood in Noah’s day was a local flood and not a global flood.
But don’t you see that makes absolutely no sense!
Why would Noah spend about 100 years of his life building a huge ship without power tools and machinery, if all he had to do was move several hundred miles to higher ground?
As I have already written above, but you have failed to address, I will add bold text to make the parts of the relevant text more obvious for you.
The rivers named in the Bible for the preflood period such as the Tigris and the Euphrates would not be the same rivers in the same location post flood. The global flood was catastrophic, responsible for depositing uncountable trillions upon trillions of tons of sediment and fossils, all over the planet that was completely reshaped from a single land mass surrounded by ocean to the world we know today with multiple continents. Right now, there exists coal and oil in sedimentary strata in Antarctica, under the ocean basins and on all continents, a fact that is totally consistent with the fact of the global flood about 4,500 years ago. The tectonic movements alone that ripped the land apart would have totally destroyed the preflood world, so that all that remains now is sedimentary strata and well preserved fossils.
Genesis 7
20 The water prevailed fifteen cubits higher, and the mountains were covered. 21 So all creatures that moved on the earth perished: birds, livestock, animals, and every swarming thing that swarms upon the earth, and all mankind; 22 of all that was on the dry land, all in whose nostrils was the breath of the spirit of life, died. 23 So He wiped out every living thing that was upon the face of the land, from mankind to animals, to crawling things, and the birds of the sky, and they were wiped out from the earth; and only Noah was left, together with those that were with him in the ark. 24 The water prevailed upon the earth for 150 days.
Genesis 8
21…the Lord said to Himself, “I will never again curse the ground on account of man, for the intent of man’s heart is evil from his youth; and I will never again destroy every living thing, as I have done.
22 While the earth remains, Seedtime and harvest, Cold and heat, Summer and winter, And day and night Shall not cease.”
Why do you not understand that the flood was global and destroyed every living thing?
Surely you can see that the texts above in Genesis 7 and 8 make it absolutely clear that the flood was GLOBAL. The whole planet was underwater.
Fact: There is enough water right now to submerge the entire planet to a depth of about 3 kilometres if the planet surface was smoothed out to a constant surface level of the Earth in all directions.
In other words the water of Noah’s flood is still there to this day, it is just that it is now partly in deep ocean basins, some in the polar and and high mountain ice caps, some in freshwater lakes and watercourses, but mainly in the crust the rocks are saturated to great depths far deeper than the ocean basins.
