IOW the Orthodox Jewish Bible and the KJV say the flood was only 15 cubits high, and all the land animals died within the flooded area since all the highest hills within the flood zone were covered.
The only version that counts is the Hebrew text, which also says the flood was only 15 cubits high, and presumably as measured on a flood level gauge.

Any other interpretation is pure fantasy and totally meaningless with zero credibility.
False,
they say the mountains and high hills were covered and if you take into account all the flood text this confirms this.
19 And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven, were covered. 20 Fifteen cubits upward did the waters prevail, and the mountains were covered.
. . . and the following in the Orthodox Jewish version confirms this, which all you have offered is stonewall denial to justify your agenda.
21 And all flesh died that moved upon the earth, both of fowl, and of cattle, and of beast, and of every creeping thing that creepeth upon the earth, and every man:
22 All in whose nostrils was the breath of life, of all that was in the dry land, died.
23 And every living substance was destroyed which was upon the face of the ground, both man, and cattle, and the creeping things, and the fowl of the heaven; and they were destroyed from the earth: and Noah only remained alive, and they that were with him in the ark.
24 And the waters prevailed upon the earth an hundred and fifty days.
Orthodox Jewish Bible
19 And the waters rose exceedingly upon ha’aretz; and all the high hills, that were under kol HaShomayim, were covered.
20 Fifteen cubits upward did the waters rise; and the harim were covered.
21 And kol basar perished that moved upon ha’aretz, both of Oph, and of Behemah, and of Beast, and of every Swarming Thing that swarms upon ha’aretz, and kol haadam;
22 All in whose nostrils was the ruach chayyim, of all that was in the dry land, perished.
23 And every living creature was wiped out which was upon the p’nei haadamah, both Adam, and Behemah, and the Remes, and the Oph HaShomayim; and they were wiped out from ha’aretz: and Noach only remained alive, and they that were with him in the tevah (ark).
24 And the waters flooded upon ha’aretz a hundred and fifty days.
I believe ha’aretz refers to the whole earth.
