Could the flood have been exaggerated?

There is no evidence at all for a global flood, (difficulty of putting all the species on the planet onto an ark is another issue). Geologists have a good understanding of the Earths processes for the last billion years or so. Had a global flood happened this would have been verified by the scientific community, but it has not. It is not because they wish to diss the bible, they do not, but just because the evidence is not there. Both the Old testament and the Koran refer to a great flood. Such a flood would require more water than exists on the planet which begs the question of where it came from and where it went. Of course you could say God did this but that is not really common sense.
Without calling religious people stupid as I know they can be misguided but not stupid I offer this explanation.
There was a flood in the local region and the local animals were put onto a large boat to save them for the local tribes: this does not imply a world wide flood. It must be remembered that the religious in those days had no concept of the world being a globe, so the world they refer to is their little world in the middle east somewhere. It is parochial knowledge, and to put animals on a boat is no different to farmers putting animals on high ground here when a local flood occurs.
