older than the Cainozoic [less than
65 Ma].” 15
How could these landforms
have survived for so many eons,
given the fact that they are eroding
today at relatively high rates? It is
possible to claim that continuous uplift
rejuvenates mountain ranges, but that
would not account for the preservation
of old planation surfaces or inselbergs,
which would have continued to erode
away. Since many mountain ranges
still have mountaintop planation
surfaces, 16, 17 rejuvenation is not a
Any new suggestions for
I have previously dealt with various
mechanisms that could possibly reduce
surface erosion rates. These include a
resistant cap rock, a dry climate, and
preservation by glaciers. I also pointed
out that within the long-age paradigm
Australia’s mostly dry climate today
was not always so in the past. 18
According to plate tectonics, Australia
was recently in the wet mid latitudes
where erosion would have been faster.
Twidale and others continue to
search for preserving mechanisms,
believing the dates are absolute and
there must be an explanation because
the landforms still exist:
“Yet, many features that are several
tens of millions, or even a few
hundreds of millions of years old,
remain incredible. On the other
hand, it can be argued that since
these landforms exist, they must be
This is the logical fallacy of
begging the question.
In his most recent article Twidale
now seems to downgrade the activity
of rivers and streams:
“Third, though widely active in
shaping the land surface, rivers per
se are not as effective as has been
supposed (e.g. Baker, 1988).” 20
He hangs onto the idea of resistant
rock at drainage divides, but he overlooks the consequences that slow
erosion at these locations would only
preserve ridge landforms longer. It
does not help the preservation of many
other landforms, such as planation
surfaces and inselbergs, which are
extensive in Africa and Australia.
Powerful, objective evidence
against deep time
What are claimed to be ‘very old’
landforms, especially planation surfaces and inselbergs, continue to be
objective evidence that the reliability
of radiometric and fossil dates is
greatly exaggerated. 18 According to
erosion rates today, there should not
be any planation surfaces older than
a few hundred thousand to a few
million years within the uniformitarian
timescale. This result confirms what
creation scientists have been saying for
years; that there is something seriously
wrong with dates that number in the
millions and billions of years. This
agrees with the RATE (Radioisotopes
and the Age of The Earth) project
which demonstrated radioactive dates
have serious theoretical problems, and
proposes that there was a period of
accelerated radiometric decay during
the past approximately 6,000 years of
biblical Earth history. 21, 22 However,
the origin of landforms that are
difficult, if not impossible, to explain
by uniformitarianism, can be readily
explained by Flood runoff. 23, 24
