Genesis 6:7 And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.

Genesis 6:17 And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die.

Genesis 7:6 And Noah was six hundred years old when the flood of waters was upon the earth.

Genesis 7:10 And it came to pass after seven days, that the waters of the flood were upon the earth.

Genesis 7:17-24 And the flood was forty days upon the earth; and the waters increased, and bare up the ark, and it was lift up above the earth. And the waters prevailed, and were increased greatly upon the earth; and the ark went upon the face of the waters. And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven, were covered. Fifteen cubits upward did the waters prevail; and the mountains were covered. 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: All in whose nostrils was the breath of life, of all that was in the dry land, died. 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. And the waters prevailed upon the earth an hundred and fifty days.

Not just regional. All of the earth.

regarding Genesis and other early books of the Bible;
What would have been the definitions of a "day", or a "year" during their times?
I often wonder if these early accounts have different references to "time" than our current understanding...
Noah lived 600 years, but how long was a year to them? The calendars of ancient times would have been different than ours, right?

just curious and looking for Biblical insight..

“Fifteen cubits upward did the waters prevail; and the mountains were covered.”

that’s pretty specific...hard to turn that into an ‘allegory’

[TXnMA]

Fifteen cubits upward did the waters prevail;

The "cubit", typically used to calculate the size of Noah's Ark is 18 inches -- or 1.5 feet.

A fifteen cubit flood would be 22.5 feet deep.

That is directly from Genesis.
