text: how did the fresh water fish survive during the world wide flood of noah? i believe the bible is truth and that it states the entire world was flooded.  given that starting point i am asking my question...  (i.e. i am not interested in answers that deny the truth of the bible by saying the flood was local:)  see this for proof of the bibles statement of a world wide flood: gen 7:19 "and the waters prevailed so mightily on the earth that *all* the high mountains under the *whole* heaven were covered." i think that when he refers to fresh water he means rivers not fresh without salt...but like that you can ask another question! how did man survive the ice age, how can people survive 14 days under ruins without food or water?by adapting or by inexplicable resistence under extreme conditions!perhaps they went to the place from where the river sprinkled from the mountain..who knows.
