As you learned, it never speaks of a worldwide flood. The word used for "world" by the Israelites was never used in the flood story.
so far I have shown where the natural reading of Genesis presents a world wide flood. The language tells of it.
I have shown where you were mistaken by presenting verses containing the word "eretz"...which you said only meant "land". In other words the text in other portions of the bible proved you to be incorrect...yet you continue to use that argument.
We can even step it up a notch...Peter in his books refers to the flood as being world wide.
2 Peter 3:4 “Where is the promise of His coming?” they will ask. “Ever since our fathers fell asleep, everything continues as it has from the beginning of creation.” 5 But they deliberately overlook the fact that long ago by God’s word the heavens existed and the earth was formed out of water and by water, 6 through which the world of that time perished in the flood.
It's there Barbarian...world.
The local flood sect was predicted as "they deliberately overlook the fact"
2 Peter 3:11 clearly adds to the concept of a world wide flood.
11Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives
12as you look forward to the day of God and speed its coming.
b That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat.
13But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells.
The verse above mentions a new earth...the first earth was destroyed by water....our current earth will be destroyed in a different fashion.
More from Peter....
2 Peter 2:5
if He did not spare the ancient world when He brought the flood on its ungodly people, but preserved Noah, a preacher of righteousness, among the eight;
It's there Barbarian...world.
Even the author of Hebrews presented the flood as world wide.
Hebrews 11:7
By faith Noah, when warned about things not yet seen, in godly fear built an ark to save his family. By faith he condemned the world and became heir of the righteousness that comes by faith.
Now, if you find that unconvincing...lets go back to Genesis where a world wide flood once again is mentioned along with a promise:
Gen 9: 8Then God said to Noah and to his sons with him:
9“I now establish my covenant with you and with your descendants after you
10and with every living creature that was with you—the birds, the livestock and all the wild animals, all those that came out of the ark with you—every living creature on earth.
11I establish my covenant with you: Never again will all life be destroyed by the waters of a flood; never again will there be a flood to destroy the earth.”
12And God said, “This is the sign of the covenant I am making between me and you and every living creature with you, a covenant for all generations to come:
13I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth.
14Whenever I bring clouds over the earth and the rainbow appears in the clouds,
15I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life.
16Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all living creatures of every kind on the earth.”
The bible speaks of a world wide flood...
