Yeah but no but yeah but God just fixed it all.
I remember an "argument" (more like a comedy routine) with a cretinist member of the extended family. She wasn't actually intelligent enough to argue with, so I was just poking the bear a bit, to my sister's chagrin as it occurred at her dining table. I brought up the improbable number of species Ol' Noah would have had to collect, and she said he didn't have to get every species, just every kind. She further explained that it only took two of the horse kind, and after they landed God made donkeys, mules, and zebras from the horses. Same with bears - you only need two - then God makes grizzlies and blacks and whatnot. Except polar bears, I imagine, as they were scared white by jangling keys. Monkeys too (which in her mind included apes, lemurs, and probably all other primates). Get a couple of chimps, then make them bigger (gorillas), or smaller (howlers), stretch their arms (orangutans). And so it goes.
The best, though, was how all the animals got from Mt. Ararat to Australia, Antarctica, South America,etc. Ready? Ice floes. Yep. They got on ice floes (move to the front, please, no shoving!), and God floated them to the proper place.
You can't make it up. Maybe Pratchett could, but no one else.
