"distantly recall the flood but contain unrealistic details."

As opposed to "realistic details" like covering the entire globe to a height of more than 7 miles? (Everest)

Or lions on the same vessel with antelope and sheep eating pancakes (or whatever was offered them) instead.

Or Noah walking to Australia and picking up all those marsupials which were all created on one day, fully formed, before the flood AND THEM ALL WALKING BACK to Australia without settling in somewhere else?

It is pretty obvious that this event happened in a supernatural way. Natural laws as our science knows them do not apply.
