Then please provide some scripture passages which seem to buttress your position.
My assertions are based upon what scripture states.
Yours, however, are not only repeated, but lack a reference....probably because you are a little uneasy about providing a source, as it would most likely expose your YEC approach to the topic......yes?
Let's see what you have...
Let's get in order what my position is. I believe the Flood was a worldwide event, and destruction was total, except for isolated pockets. (Call that A). Two others have been advanced: That there were no isolated pockets, the destruction was totally worldwide (B). That it was only local, this is your position (C). The people who believe B have provided so many Scriptures, it's ridiculous for you to ask me. I provided my evidence against them. Any of their Scriptures prove you wrong. You are asking me to prove a position I do not espouse.
It is clear, the Bible says that the "earth" was the target of destruction. The Scriptures are clear on this. The only question is whether Hebrew "all" means "all" or "most". My evidence is historical, and demonstrates it only means "most".
Nevertheless, you want Scriptures, I will give you a few, and you will disagree with each. You argument is with the people who believe B. The first proof is Gen. 5, just read how long everyone lived. If each child has just 2 children and no one ws dying, and they marry at age 14, in that time you get 2 to the 63rd power people. This is about 1,000 to the sixth power, or 1,000,000,000,000,000,000. This is a billion times the population of earth now. Even if you go with the 120 year figure of Gen. 6, 2 to the 120th power is 10 to the twelfth, which is the 140 times the population of earth now. It's pretty clear each one had "sons and daughters" so they had more than two children. Since there is no mention of killing again until Lamech, there could not have been too much of it. It's thus seems pretty clear that some of them were dying early. But even allowing for all that, they would not have all fit in the area you claimed. Sheer numbers force the migration.
The next proof is Gen. 6:1, which demonstrates that your assertion, that they did not follow God's command to multiply until after the flood, is incorrect.
Finally, Gen. 10:5 tells us that within the second generation after Japheth (who got off the ark with his wife) there were already many lands inhabited by Gentiles, and they already had separate families, languages, and nations. This is clearly a different allotment of the lands from that of Dt. 32:8, domnstrating that there was another plan before the Flood (God's), and that could only have been pre-flood, since the new one happened very soon after.
Although it is beyond me why you will not accept historical evidence of history, but insist the matter be proved from the Bible, which is not primarily a historical book.
