Please tell me how old the Appalachain mountains are.
Next, please tell me which generation of Appalachain mountains we currently have.
Third, please tell me where all the soil of the east coast came from if not from the mountains.
As to why mountains are high, here's a hint for you. The indian plate is shrinking. But Everest isn't growing higher. Why?
If plate tectonics can build mountains (which it can and does), what's to stop it from exceeding the rate of erosion? What's to stop mountain building from delaying the effect of erosion--that is, why do the mountains not shrink as fast if only erosion was occurring?
Third, erosion rates are highly variable--fastest in places with moisture, slowest in the driest places.
2. How is your model any more viable than mine which depicts an undeterminate timeperiod of soupy mix on earth being churned by seismic activity etc so as to grind up the rocks & pebbles into sand etc?
This is nonsense. Our model is viable because we can observe it (and have). We know that these processes occur and how they work. Your's is not for a simple reason--how does a liguid behave when shaken? How do solids in a liquid behave when shaken? Oh wait, solids sit in the bottom of the jar (assuming they have greater density than water, which all but one rock does, and that's a volcanic rock). So now you have to get sand from the bottom up. Where does this occur? How does/would this occur?
