hehehe, my favorite was the erosion of the soil. This guy does not understand erosion rates at all does he?
Actually, if you use erosion rates *only,* then, yes, the world couldn't be much more than 100,000 years old. At observed rates of erosion, in another 100,000 years, the Alps, Himalayas, Rockies, and Andes would all be ground right down to sea level.
Only when you factor in mountain-building processes, which weren't really well-known until very recently, do you bypass this critical problem in the age of the earth.
(Volcanoes don't work; they produce the wrong kind of rock, and too slowly.)
re the Moon, my *guess* would be that, over time, the dust compacts into a more and more solid kind of substance. Is that even close to correct?
