Seashells on a mountaintop? Guess I'd better stop eating oyster p'boy sandwiches. No telling what they'll take oyster shells in the middle of Texas to be the proof of.

We find coral around St. Louis routinely. The middle of the US used to be a shallow sea. I love giving chunks to my cousins and explaining where it comes from. 

Really? That is fascinating. I always wondered if the Appalachians and Rockies aren't the result of 3 land masses coming together to form one supercontinent (Wilson Cycle).

It's likely a majority of what's above sea level now was underwater - at some time in Earth's history.    We have evidence of many types of mollusks, including bivalves, cephalopods, and gastropods from the Cambrian (half a billion years ago, give or take a few dozen million).

Most of the mountain ranges on Earth are younger than that, much younger.  The dry surface of Earth has changed substantially in that time, no goddamned global flood needed.

And yet, contrary to the Genesis creation story, the Earth didn't began covered with water and then dry land appeared. The Earth began as a ball of molten rock. Not until it became cooler and larger did it have enough mass/gravity to keep an ocean on its surface.
