Since the Bible said it was global then the Bible was in error. Since the Bible said donkeys and lizards talk the Bible was in error. Since the Adam & Eve and Noah scenarios are not genetically viable the Bible was in error. Since the Earth is not a flat square circle at the center of a geocentric universe the Bible was in error.<quoted text> Was there a flood or not?
The answer is, there was flood and the bible said so.
The issue is, whether it was global or regional.
To me, i believe the people then thought it was global, this does not mean that the bible is in error.
The magnitude of the flood led to that conclusion.
I understand your wish to make allowances for the ignorance of primitive goatherders who didn't get out much but you can't say that the Bible "Word of God" then blame any "minor" errors on the goatherders who wrote it.
