I must point out that you have failed to give a single citation for
your claims. In fact, the truth is that every single one of your
claims is entirely false. This is incredible how young earth
creationists can misrepresent matters so badly and so blatantly.

Look at the complete difference between the surface of the moon,
which has for the most part only one "erosion" process, which is
simply further impacts that may occur which will "erode" previous
impact craters. The moon has no atmosphere, no weather, no rivers,
no oceans, no active geological processes, so on the moon (which is
much smaller than the earth and thus has much less surface area and
much less gravity, which means it has experienced far fewer
impacts) we see thousands of impact craters, because they aren't
eroded away since erosional processes on the moon or almost
nonexistent today. We do *not* see such a fantastic number of
impact craters on the earth precisely *because* they've been eroded
away, and it takes far, far longer than 20,000 years for impact
craters to be eroded to nothing.

There is a vast difference between the Barringer Crater near
Winslow, Arizona, which was created about 50,000 years ago, and the
much older and much larger Vredefort Crater in South Africa. The
Barringer Crater is about 1 mile in diameter, and at 50,000 years
it has experienced relatively little erosion -- relative to the
Vredefort Crater. The Vredefort Crater is over a hundred times
large than the Barringer Crater, but at over 2 billion years old
its surface features have been all but obliterated by erosion.

Among the links below, note the huge difference between the
Barringer Crater and the Ries and Steinheim craters, due to the
fact that these two craters have experienced erosion for a far
greater length of time than the Barringer Crater.

And yet, Gary, you are pretending that there is little difference
in the erosion of impact craters. Yet again do I point out to you
and to everyone else that there is the dream world of YEC, and then
there is the reality that the rest of us talk about, and these two
are very different. When are YECs going to wake up and smell the
coffee?
