I've heard the statement from bible apologists so many times that the global flood story of Genesis was not a global flood but was probably a local flood. This seems problematic.
- This directly disagrees with the bible. Everywhere the bible internally references a global flood of worldwide scale (I'll throw in Matthew 24:39 as a NT example and Genesis 6:17 as a OT example.)
- If it was just a local flood then God could not then say: "And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh." Since we have terrible local floods every year (e.g. http://www.bbc.co.uk/news/world-latin-america-12263166 Brazil flood deaths top 800 with 400 still missing) so then God must be a liar or it was indeed a global flood.
We are then left with the obvious conclusion:
- Since there was no global flood recorded in the geological evidence as read and understood by the overwhelming majority of geologists this means the bible story is just that - a made up myth.
- Since that myth contains the words of Jehovah we have cast iron proof that the words of Jehovah as recorded in scripture are - at least in this instance - made up completely by men.
- Since no prophet - including Jesus - pointed this out then they either did not care about the lies or did not in actual reality have any spiritual gift of discernment and they were just making things up (hence why they happily included the myth in their 'revelations.' There is no evidence that Jesus was indifferent to scriptural interpretations; the recorded Jesus was always arguing about the fine details - even at 12.
- Anyone who believes in a literal global flood is deluded and their judgement regarding anything found in the bible is equally suspect.
- Anyone who believes in the bible doctrinally but not historically is making the impossible assumption that the doctrine is correct while the history is a lie. They cannot be trusted either as they have used their own understanding to judge the supposed 'word of god'.
- Anyone who believes in most of the bible but is willing to accept scientific / rational / logical re-interpretations of key scriptures over and above the actual words of the bible are not actually bible believers at all, they are believers in their own made up philosophy that is merely an eclectic series of borrowings probably ranging from the sermon on the Mount to the Tao of Pooh with a few pithy sayings derived from fridge magnets thrown in.
The flood myth destroys utterly the Christian, Jewish and Muslim myths.
