It's obviously debatable - but we know that there was a huge flood at the end of the Ice age that would have raised the sea level considerably in a relatively short period. This is about 12,500 years ago. There is also evidence in India, and in the Indian ocean, for civilisation there at that time. And finally that particular myth of a huge flood is found in pretty much every culture. So maybe there was a guy called Noah, maybe there wasn't. But I strongly suspect there was an actual world wide flood within the mythic memory of our species.
