Noah's flood. Entire earth. Animals on the Ark.
The miracle of the skybow rests on it's context.
It is quite straight foward, isn't it?
A global flood is also straight forward when you incorporate jovian masses with periodic orbits - especially considering the binary jovian companion of our sun not too far outside of our solar system. Gravity potentials, as well as electromagnetic flux, and simple celestial projectiles can cause the global event - which can be shown to have a quantifiable affect on a chosen respective system, or the total system.
Even non-biblical documents about the Exodus in Egypt speak about a Destroyer in the sky that looked like a dragon, cause [the] upheaval in Egypt, the seismicity that "parted" the red sea, and how the "slaves' god magic was more powerful than the Egyptian gods' magic."
In fact, the Exodus plagues was God's direct challenge and assault on the "power" of the 10 principal gods of Egypt - including Pharaoh (god on earth.)
And, Noah built a gargantuan multi-level ocean liner with gopher wood - a wood whose strength is supreme, and whose
density is very low (so that the maximum allowable mass per volume of the vessel will maintain equilibrium with the water level to float.)
Even the dimensions of the ship are in the canon - so that one can compute the size of the vessel. In the Apocrypha, Noah had help - including instructions and teachings from Enoch
after he was caught up the first time and brought back to Earth to deliver the "books of Enoch" (before he was caught up, again and gone for good.)
But, you don't need the canon to deduce the flood was global. It is my understanding I addition to the water cap falling and the windows of heaven opening to flood the earth, the fountains and spring systems on earth were also part of the global flood. It wasn't just a local event.
We can also determine this was not a local event based on reading the canon. Firstly, we know Cain went East to Nod - and did "his own thing." The world was a global entity, and there were advanced civilizations on the planet. For ten generations, the children of Adam did not stay in one place. We know this isn't true, because at least most all of the children of Adam that were alive during the time right before the flood were scattered within the world - contributing to their choices to become worldly and accept what seems eerily similar to the Mark of the Beast (human genetic manipulation of DNA.)
The entire world for ten generations drove toward degeneracy - and these humans back then lived for several hundreds of years (consequence, I think, of coming off of fresh perfection.) So, a generation was not simply 40, or 70 years. Adam and Eve were 130 before having Seth, and the rest of Adam's children waited similar lengths of time before having their children.
So, this was a 1300 year event buildup (how much have us lowly humans with a literal fraction of that lifetime spread out over the world in any given 1300 year interval of time in history?) In 500 years - with slaves like the other ancient nations - America became a world empire - and the sun does not set on the US like Rome used to boast.
So, I think beings fresh off of perfection with much longer lifetimes (and, I would argue much more intelligence than the "smartest" modern human) would have easily migrated to every corner of the earth - even for the simple purposes of curiosity and exploration. And, therefore in order to get rid of the entities that were no longer human because of their choice to accept transhumanism, the Flood was global.
Now, the interesting thing about the Nephilim, Rephaim, Anakim (JEDI, skywalkers) and Emim existing AFTER the flood is that, IIRC, the bible (or apocrypha) mention that NOAH, and HIS SONS were perfect in their generations. It didn't say anything about the wives. This is a subtle hint - like the subtle hint that the genealogies of Adam begin with Seth, and Cain has no lineage listed beyond him (i.e. Adam is not mentioned in his genealogy as the father of Cain - like it does with Seth.)
As I said, I believe there is more than enough information in the canon to deduce this, but it does help other apocryphal, historical, mythical and mystical texts provide details that could prove to be insightful.
