Granny, I agree. The story does not seem to make sense if it was a local flood. Granted, the "world" most likely was believed to be quite small compared to what we know today. But, it appears through scripture the authors believed in quite a few things about the flood.
Genesis 6: 12 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth.
13 And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
The very reason for the flood was due to mankinds wickedness. Not a certain amout of people, but mankind. Only Noah and a few others were chose to survied.
Genesis 7: 21 And all flesh died that moved upon the earth, both of fowl, and of cattle, and of beast, and of every creeping thing that creepeth upon the earth, and every man:
All flesh was killed.
Genesis 9: 1 And God blessed Noah and his sons, and said unto them, Be fruitful, and multiply, and replenish the earth.
Seems odd that millions surived, but it was up to Noah and his sons to replenish the earth.
The very purpose of taking male and female animals was to replenish their kind. Obviously if it was local, this would not be necessary.
If it was local, why could they not find land for a year?
Also, if the flood was local, what about gods promise? That the rainbow was sign that god would never flood the earth like that again? If it was local, theres a huge problem. There have been other deveasting floods. Did god lie?
Even "Peter" believed it was "world" wide, all perished.
And God did not spare the ancient world--except for Noah and the seven others in his family. Noah warned the world of God's righteous judgment. So God protected Noah when he destroyed the world of ungodly people with a vast flood. 2Peter 2:5.
