Gen 7:19,20 NWT: 19 And the waters overwhelmed the earth so greatly that all the tall mountains that were under the whole heavens came to be covered. 20 Up to fifteen cubits the waters overwhelmed them and the mountains became covered.
That is why everyone assumes that. Or why Biblical literalists do. And why people who make fun of Biblical literalists operate on that assumption.
under_believer,
I know but the verse is only discussing that part of this Globe where Noah and the sinful humans that died lived. Only the animals within Noah’s jurisdiction and immediate reach needed to be taken into the ark as he did not travel to what is now Australia or anywhere else so far away. The whole heavens represents such humans that sinned and not the planet itself. Yet most keep thinking the entire Globe was engulfed? There were endless discussions on this here on JWD years ago and AlanF argued successfully against such Global thinking. Why? Because words such as earth and heavens have many definitions other then the common ones we tend to use. Most choose to ignore this fact but take a look at the word earth for example:1
) land, earth1a) earth
1a1) whole earth (as opposed to a part)
1a2) earth (as opposed to heaven)
1a3) earth (inhabitants)
1b) land
1b1) country, territory
1b2) district, region
1b3) tribal territory
1b4) piece of ground
1b5) land of Canaan, Israel
1b6) inhabitants of land
1b7) Sheol, land without return, (under) world
1b8) city (-state)
What ever happened to country, territory, district, and other such localized locations? Where in scripture does it force an interpretation that includes the entire Globe most of which was still uninhabited by humans? Why does everyone deviate from the context and circumstances in which the instructions were given to Noah? Even simple examples of animal life as given here in this thread refute the common teachings that prevail in our day that the flood was global. I just wanted to bring this into focus for the group under_believer and thank you for responding to it.
