two important questions for Servant

You don't need a worldwide flood to see for yourself that gravel sinks faster than silt. You don't need a worldwide flood to watch how fast coral grows today, and to see that a 1600-foot-tall reef would be tough to grow in a year, or even in a millenium.

And you have heard of winter, have you not, Steppjr? In that time of the year, in many parts of the world, water vapor floating around in random order somehow orders itself into snow crystals, thus reducing entropy!!! We know this is not possible, so Ice Faeries must be causing it by.....

Call me when you're ready to go.

Or, just as likely, what if the Big Guy shows up and says, "Yeah, I did it all with evolution. Those bronze-age sheepherders made all that 'six days' stuff up on their own."

They don't fit "without any contradiction." There is even a recent case where some nasty-looking little sea creature that was thought to be a mullosc, I think it was, but turns out on the basis of DNA to be more like an acorn worm or suchlike, and possibly a new phylum of its own. Bats have turned out to belong to two seperate Classes instead of one, as morphology once had it figured. So no, the fit isn't perfect. But of course, the surprises are what make news, and the "we already knew that"s don't.
