If the flood is only localized, then the meaning that the Bible assigns to the flood doesn't make sense:I believe they are multiple reasons to believe in a localized flood, including:
A localized flood would also mean that the ark would have to carry significantly less species of animals, predators from the ark would be able to eat animals from other regions, and the inhabitants of the ark would not have to survive entirely by themselves after landing.
- The seaworthiness of Noah's ark (Noah’s Ark and Naval Architecture — Watchtower ONLINE LIBRARY). There are not many feasible ways that Moses (the supposed author of Genesis) was an expert when it comes to seaworthy vessels.
- An imprint, roughly the size of Noah's ark, found on Mount Ararat, Turkey. (Evidence ‘one step closer’ to Noah’s Ark final resting place | SUGA Magazine Online).
- Flood myths from many different cultures (Flood myth | mythology).
Random Viewer: But IsaiahX, the bible says that the waters covered the whole earth!
Me: The Hebrew word translated world (אֶרֶץ) means land or country (Strong's Hebrew: 776. אָ֫רֶץ (erets) -- earth, land) If someone says that one farmed the land, for instance, they usually don't mean that they planted on every location around the globe, including Antartica and separate continents. They just mean the immediate area, at least most of the time.
Genesis 6:5-8:
If the flood was only localized, then the message behind it can't be "God thought humanity was so wicked that he decided to wipe it from the Earth." Instead, the message becomes something like "God thought that most of humanity was worth saving, so he decided to scare them a bit to bring them back in line."5 But the Lord saw that the wickedness of humankind had become great on the earth. Every inclination of the thoughts of their minds was only evil all the time. 6 The Lord regretted that he had made humankind on the earth, and he was highly offended. 7 So the Lord said, “I will wipe humankind, whom I have created, from the face of the earth—everything from humankind to animals, including creatures that move on the ground and birds of the air, for I regret that I have made them.”
8 But Noah found favor in the sight of the Lord.
This reminds me of the people claiming to have found the bones of Jesus. Like these "localized flood" claims, the people making them really haven't thought things through if they think the claim supports their religion.
