Guess what? A planet which was once covered in ferns at the poles then suddenly and repidly completely flooded to the point where evidence of sea shells are found at the top of Mount Everest WAS in your understated words, "a mess." Ya think?? Planet Earth is proven to undeniably become an altogether different planet after the Great Flood.
Standard evolutionary and geologic theory addresses almost all questions with a single simple theory requiring few assumptions, chiefly that the physical laws that obtain now also worked in the past.
Gee, I'm sorry. That's pure balderdash.
"Evolution" is JUNK SCIENCE.
CHALLENGE: Please provide a single provable instance of "standard evolution."
As to the rest of your post, it's the usual mumbo-jumbo word-salad of having explained absolutely NOTHING regarding "physical laws." Moreover, your word-salad answered not a single question with respect to defining your "simple single theory" that a pre-Flood world was no different than a post-Flood world. You couldn't be more wrong.
Well, no, because the Great Flood isn't proven to have happened. The Flood is a good example of a one-off explanation that requires other one-off explanations on top of it. Why are there sea shells on top of mountains? The Flood put them there! Why aren't there horse bones mixed in? Uhh...they swam away, that's the ticket! Why are there all these fossils mixed together in this lake bed? The Flood! Why aren't there any dinosaur bones mixed in too? Uhh...
