(the Grand Canyon has both?so the uplift ?millions of years? argument is not very conclusive).
By the same token, the spillway argument is not very conclusive. Clearly, since it contains feature of both spillways and long, meandering river carving, it can't be used to confirm either theory. It's just not a very clear-cut case, by your argument. Thus it's a little disingenuous of you to use it as evidence for your position, since you said it couldn't really be used as evidence for any position.
Where is Mexico, Guatemala, Honduras, Costa Rica, Panama, Belize? They?re not there!!!
Also, if pangea is true, then perhaps you could explain WHY they would have had to shrink Africa 30-40 percent to make them fit together in the picture?
You remember that plate tectonics we keep talking about, where the Earth's plates keep running into each other and lifitng land masses above the oceans? So, why would you assume that all present land masses would have to have always been there? Some of the land masses have arisen since Pangea's breakup.
You may be interested to know that Africa is growing. There's a rift in the middle of it (the Great Rift Valley) where the plates are slowly drawing away from each other. It's an area of intense vulcanism. Thus, if we extrapolate backwards, we find that Africa would be smaller at the time it was a part of Pangea.
So far you've yet to present any kind of geological evidence that hasn't been the result of your failure to consider plate tectonics. Is there something about tectonics you reject?
And uplift COULD NOT have caused the clams to be there, because the clams are closed. You see, when a clam dies the muscle relaxes and the shell opens.
Your argument here doesn't make any sense. Death is death. If what you say is true than they couldn't have died from a flood, either. No matter how catastrophic the flood was, it couldn't have resulted in instant fossilization - if every clam dies with an open shell, then even clams killed by your flood should have open shells. Clearly, then, it's possible for clams to die with closed shells.
We know that the Himalayas are uplift mountains. We've observed them growing, ever so slowly. There's nothing in your evidence to suggest that the clams didn't die and get fossilized on an ocean floor that much, much later became a mountain due to uplift. Your argument is simply fallacious.
