Genesis 7:14 tells us Ha-Geshem הַגֶּ֖שֶׁם "The-Rain" was on the earth forty days and nights (וַיְהִ֥י הַגֶּ֖שֶׁם עַל־הָאָ֑רֶץ אַרְבָּעִ֣ים י֔וֹם וְאַרְבָּעִ֖ים לָֽיְלָה), and the sea level reached 15 Cubits (22.5 Feet) above all mountains on earth in Genesis 7:20 :
[Bereshit | Genesis 7:20] "Fifteen cubits above did the waters prevail, and the mountains were covered up." (חֲמֵ֨שׁ עֶשְׂרֵ֤ה אַמָּה֙ מִלְמַ֔עְלָה גָּֽבְר֖וּ הַמָּ֑יִם וַיְכֻסּ֖וּ הֶֽהָרִֽים)
Now if the height of Mount Everest (29,031.7-Feet) is considered in the rising sea levels of "The-Flood" הַמַּבּ֣וּל Ha-Mabul : https://en.m.wikipedia.org/wiki/Mount_Everest
Did 29,054.2-Feet (29,031.7 Feet + 22.5 Feet) of גֶּ֖שֶׁם "Rain" fall during הַמַּבּ֣וּל The-Flood, based on Genesis 7 verse 20?
