Evidence would be things like the Grand Canyon
How is it supposed to have formed during the flood? It's meandering and has vertical slopes. It's also cut deeply into the vishnu basalt. It basically screams "i took millions of years to form".
And why is it unique if the flood was supposed to be global? There should be many such canyons all over the world then.
Before the Flood peolpe lived longer lives. And there may have been no polar ice caps. This would resort in a dense misti environment with a stronger oxygen level. Sorta like a yearly rain forest, which would contribute to longer lives and were the water is.
The atmospheric pressure of sufficient water being solved in the atmosphere would have killed every human life at that time, and the energy released in its downfall would have made the atmosphere's temperature rise to hundreds of degree, thus cooking everyone.
And oxygen actually is toxic in high concentrations, and it does nothing to stop the degradation of telomeres, which is one of the main reasons why people age.
Genesis
19And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven, were covered.
Now the highest hills.
Does that not totally defeat the point of the flood and the ark if not the whole earth was covered?
And the bible quite clearly states that the whole earth was covered:
Genesis 7:23 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.
20 Fifteen cubits upward did the waters prevail; and the mountains were covered.
One the waters power could cause immense errosion causing 1,000's of feet to appear,
Huh? How is that supposed to work? Erosion removes ground and moves it to lower altitudes, it does not form mountains.
or no 2 the waters could cause cracks in the ground causing the plates to shift pushing up the mountains further.
Impossible and there is no evidence supporting this whatsoever either.
sea shells on top of mountains like Mt. Everest etc.
Plate tectonics explains this...and it also explains the precise age of these fossils.
And how are corals supposed to have survived a global deluge? Even minor changes in salinity and temperature kill them.
Cubits were used by egytians. 515 feet = 1 cubit. So the highest of any known mountains were 515 x 15 cubts = 7,725 feet high.
Where did you get that from?
A cubit is based on the length of a human forearm, varying in length from 1.75 to 2.25 feet.
That passage means that the mountains were covered by roughly 30 feet deep water.
More mention of mountains:
8:4 And the ark rested in the seventh month, on the seventeenth day of the month, upon the
mountains of Ararat.
8:5 And the waters decreased continually until the tenth month: in the tenth month, on the first day of the month,
were the tops of the mountains seen.
