Hi Chordateslegacy,
I fully respect what you are saying because you are quite correct about there not being a global flood as accounted in the bible,,this is because the bible dosen't actually teach a global flood, it's the Orthodox Church that teach that red herring my friend not the called out chosen elect of God.
Now if I may I will give you something to ponder and make of it what you will. First of all the days of creation were not literal 24hrs days as you already know, I have several bibles (Fenton's ,etc) that do not teach such heretical nonsense and they clearly state that the days of creation were aions, check out these scriptures (Psalm 90:4 & 2 Peter 3:8), I 'm sure you'll have a bible of some sort hanging around just in case of emergency,lol. Ok, so when the flood happened around 10,000yrs ago the earth was not as it is now, the area where Noah was was around the middle east, and that is where at that time mankind was thriving. This area which of course is vast is where the floods hit engulfing the moutainous area's of the Himalaya's, etc. Now for the supernatural in all this after all it's God doing it, so there has to be a little bit of the impossible. In the flood account if you read it carefully, especially in the Greek Septuagint you will see that in (Genesis 8:1) God caused an awesome wind to arise that actually contained the waters like a humungous lake in much the same way that He parted the Red sea but way, way bigger. A kind of suspended aquamation,lol.
So mate the flood of Noah was a localised flood not a global flood as the continents shifted. Just some food for thought although I could be just an idiot?
