If Noah left, they would have never heard Noah's preaching! They would not have been warned by the Spirit for 120 years.
if he did not spare the ancient world when he brought the flood
on its ungodly people, but protected Noah, a preacher of righteousness, and seven others." 2 Pet 2:5
Only one mountain range is mentioned in Genesis.
I once spent a day in a library learning of all the higher mountain ranges around the world. Genesis gave the exact height above the named mountain range. Some other ranges were much higher. So?
God's sovereign choice. And ,it was only animals designated to live in the same spot on earth as where man was living. For, if every species of animals we find on the earth were to be saved by Noah? He would have had to build a very large fleet of Arks. Its one reason why secular scientist smirk at the universal flood concept for Noah's flood. Its makes them feel justified for rejecting God.
Not to mention... If all the salt water merged with the massive fresh water... marine life of all kinds would have been greatly destroyed. Many would have been made extinct.
God heaped up the waters as seen in the parting of the Red Sea. God can heap up water and keep a very high flood line contained within a certain area.
God revealed this ability of His more than once. Not just with the Red Sea...
See, the ark of the covenant of the Lord of all the earth
will go into the Jordan ahead of you. Now then, choose
twelve men from the tribes of Israel, one from each tribe.
And as soon as the priests who carry the ark of the Lord
—the Lord of all the earth—set foot in the Jordan, its waters
flowing downstream will be cut off and stand up in a heap.” Josh 3:11-13
God could heap up massive waters and control the flooding within boundaries by His own power.
Read Genesis 11:1-2 tells us..
Now all the earth used the same language and the same
words. And it came about, as they journeyed east, that
they found a plain in the land of Shinar and settled there.
What constituted the "whole earth" in the ancients thinking was where man was found living. It that case, the "whole earth" was living on one single plain. The whole earth gathered onto one plain.
Now all the earth used the same language and the same
words. And it came about, as they journeyed east, that
they found a plain in the land of Shinar and settled there.
I covered that when I explained how God heaped up waters and contained them and confined the waters to a defined space on earth.
