i was remembering a story of a holocaust survivor who went home to his village and found everyone had gone. he said i could understand exactly why noah got drunk. if you imagine what it would have been like after the flood, devastation, all the swollen, bloated bodies lying around, terrible. >> and it turns out that flood stories like this are not unique to the bible. they can be found all over the ancient world. >> these stories didn't drop from heaven one time, the clump of words all sent by god in book form. these stories developed in a certain place and time. >> leading some archaeologists to believe they're based on real events. >> people do not make these things up. so does this mean that we've got a flood way back in antiquity? it may well. a story is created to explain something that happened.
