Good response, I counter that I have yet to have someone explain the Noah's ark story. Here is a discrete story that supposedly happened on earth, and there was no supernatural events in it.
I want the creationists to prove it, or to even offer evidence that is reliable and testable, and to be able to answer some questions that must arise if the story is true.
We have to explain evolution (endlessly), but they don't have to explain Noah's ark?
(other than, It was a miracle!!!)
Forget the pitstops to drop off penguins at the South Pole or marsupials in Australia. Just do that for 40 days. I won't even require them to find room for the dinosaurs.
