Flood, page-19

''I don't particularly care, all I was doing is simply relaying what I saw on the Doco, no more, no less.''

You should care about who made the documentary. If True believers, they begin with the assumption that the Flood story is true because it's in the bible, so they set out to make it look not only possible, but true. It's called confirmation bias. A common thing in matters of faith.
