I believe Noah's Flood to be a localized event and actually happened because it is a common theme throughout human civilizations emanating from the Black Sea (there are cultures that do not have this sorry so I would assume they ahd migrated out of the area before the event); to those cultures that survived the Flood, it was world-wide.
On Adam and Eve, I did read somewhere that they think they may have been either ancestors or proto-ancestors for the Caucasian race though that study was probably one of those out-there ones.
