NOAH JUSTICE: Because of
its amazing beauty and size,
00:00:10.77\00:00:13.17
Yosemite National Park was
one of the first pieces of land
00:00:13.27\00:00:16.71
set aside for the enjoyment
of the public in the United
00:00:16.81\00:00:19.71
States.
00:00:19.81\00:00:21.18
The amazing granite cliffs are
a part of the Sierra Nevadas,
00:00:21.28\00:00:25.59
a huge rock
batholith thought to have been
00:00:25.69\00:00:27.99
formed over millions of years.
00:00:28.09\00:00:30.59
But new evidence
helps researchers understand
00:00:30.69\00:00:33.33
how the formation
of these mountains
00:00:33.43\00:00:35.03
took just weeks or months.
00:00:35.13\00:00:37.77
In addition,
Yosemite Valley is thought
00:00:37.87\00:00:40.17
to have been formed by the
Merced River and multiple ice
00:00:40.27\00:00:43.61
ages over long ages.
00:00:43.71\00:00:45.67
Yet this huge
valley is actually evidence
00:00:45.77\00:00:48.54
for erosion due to a
catastrophe during and right
00:00:48.64\00:00:51.98
after the Flood.
00:00:52.08\00:00:53.48
Secular scientists have
over 60 different explanations
00:00:53.58\00:00:56.85
for how many ice
ages have been formed.
00:00:56.95\00:00:59.39
But astute researchers
recognize that the conditions
00:00:59.49\00:01:02.26
right after the global flood
are the best model to explain
00:01:02.36\00:01:05.43
the one major ice age.
00:01:05.53\00:01:08.63
Another amazing
geologic feature appears
00:01:08.73\00:01:11.33
just a few hundred
miles from Yosemite--
00:01:11.43\00:01:13.87
the great Zion Canyon in Utah.
00:01:13.97\00:01:16.64
Secular scientists
have some major challenges
00:01:16.74\00:01:19.57
explaining how the cliffs were
formed and the canyon was cut.
00:01:19.67\00:01:23.28
Huge sandstone layers, steep
canyon walls, amazing arches,
00:01:23.38\00:01:28.68
and large hanging
valleys are all good evidence
00:01:28.78\00:01:31.59
of a worldwide
catastrophe-- all this
00:01:31.69\00:01:34.36
and more next on
"Awesome Science."
00:01:34.46\00:01:41.93
"Awesome Science"
takes you on a field trip
00:01:42.03\00:01:45.07
to some of the most amazing
geologic and historical sites
00:01:45.17\00:01:48.80
around the world where we
use the Bible as our history
00:01:48.90\00:01:51.97
guidebook to
interpret what we see,
00:01:52.07\00:01:54.51
that the Bible can be trusted.
00:01:54.61\00:01:56.78
And empirical
science falls in line
00:01:56.88\00:01:58.61
with the Biblical
account of Creation,
00:01:58.71\00:02:00.72
the Fall, and the Flood.
00:02:00.82\00:02:03.65
Science, it's awesome.
00:02:03.75\00:02:05.35
Yosemite is
breathtaking from the minute
00:02:17.93\00:02:20.47
you enter her
Cathedral granite peaks
00:02:20.57\00:02:22.44
rising several thousand
feet above the valley floor.
00:02:22.54\00:02:26.14
It's no wonder
author and champion
00:02:26.24\00:02:28.41
for the national
parks, John Muir,
00:02:28.51\00:02:30.35
said no temple
made with human hands
00:02:30.45\00:02:32.61
can compare with Yosemite, where
God's attributes and glory is
00:02:32.71\00:02:37.95
revealed.
00:02:38.05\00:02:39.72
Muir believed
that the best place
00:02:39.82\00:02:41.72
to discover the true
attributes of God was in nature
00:02:41.82\00:02:45.19
and that God is always
active in the creation of life,
00:02:45.29\00:02:48.43
and thereby has
continued to keep
00:02:48.53\00:02:50.73
the natural order of the world.
00:02:50.83\00:02:53.77
About the size of Rhode
Island, Yosemite National Park
00:02:53.87\00:02:57.04
covers 1,190 square miles and is
full of valleys, giant cliffs,
00:02:57.14\00:03:03.01
waterfalls, alpine
lakes, and even active glaciers,
00:03:03.11\00:03:07.55
with its highest point
being over 13,000 feet.
00:03:07.65\00:03:12.19
Yosemite was first set aside
by President Abraham Lincoln
00:03:12.29\00:03:15.86
on June 30, 1864, and
given to the state of California
00:03:15.96\00:03:20.13
to oversee.
00:03:20.23\00:03:21.56
It was the inspiration
for the first national park,
00:03:21.66\00:03:24.67
Yellowstone.
00:03:24.77\00:03:25.17
When the National Park
Service was organized in 1916,
00:03:27.84\00:03:31.37
Yosemite was adopted
in as a national park.
00:03:31.47\00:03:35.08
It is visited by
over 3.7 million people,
00:03:35.18\00:03:39.08
mostly in the seven square
mile area of Yosemite Valley.
00:03:39.18\00:03:42.95
From the valley
floor, giant granite cliffs
00:03:43.05\00:03:45.55
goes straight up and have names
such as Half Dome, El Capitan,
00:03:45.65\00:03:49.89
and Sentinel Dome.
00:03:49.99\00:03:51.76
As one looks
around, questions are
00:03:51.86\00:03:53.60
formed about this
amazing granite rock
00:03:53.70\00:03:55.80
and how it was carved
in such a deep valley.
00:03:55.90\00:03:59.10
The granite is
thought by secular scientists
00:03:59.20\00:04:01.67
to have begun forming
over 210 million years ago.
00:04:01.77\00:04:06.94
After the
formation of the Sierras,
00:04:07.04\00:04:08.91
the valley was mostly
cut by the Merced River
00:04:09.01\00:04:12.01
and finished off
by large glaciers.
00:04:12.11\00:04:14.78
Obviously, these
time scales don't match up
00:04:14.88\00:04:17.49
with the Biblical
account of a few thousand years.
00:04:17.59\00:04:20.66
Evidence has come to
light to help explain
00:04:20.76\00:04:23.06
the quick
formation of the granites
00:04:23.16\00:04:24.69
during the Flood
of Genesis, as well
00:04:24.79\00:04:27.03
as a model for rapid formation
of the massive glaciers
00:04:27.13\00:04:30.53
and ice sheets from the ice
age not long after the Flood.
00:04:30.63\00:04:34.47
What evidence?
00:04:34.57\00:04:35.60
I'm glad you asked.
00:04:35.70\00:04:37.44
That's why a group of scientists
called the RATE group who
00:04:38.31\00:04:41.88
believe in the
Biblical account of creation,
00:04:41.98\00:04:44.28
a young Earth,
and a global flood,
00:04:44.38\00:04:46.58
challenged this
secular idea of long ages
00:04:46.68\00:04:49.55
by looking deeper
into the rocks to develop
00:04:49.65\00:04:51.95
a different and better model.
00:04:52.05\00:04:54.92
To date volcanic
rocks when they cool,
00:04:55.02\00:04:57.49
a method called a
radioisotope dating is used.
00:04:57.59\00:05:01.26
This type of dating analyzes
the radioactive elements
00:05:01.36\00:05:04.47
in the rocks.
00:05:04.57\00:05:05.70
Each radioactive
material called parent elements
00:05:05.80\00:05:08.54
decays into other elements
called daughter elements.
00:05:08.64\00:05:12.17
For example, uranium-238,
the radioactive parent element
00:05:12.27\00:05:16.54
eventually decays
into the stable daughter
00:05:16.64\00:05:18.95
element of lead.
00:05:19.05\00:05:20.52
Over 4.468 billion years,
half of uranium atoms in a rock
00:05:20.62\00:05:25.42
would turn to lead.
00:05:25.52\00:05:26.76
So it is called a half-life.
00:05:26.86\00:05:28.86
It has been
demonstrated by observation
00:05:28.96\00:05:31.09
that different
radioactive elements decay
00:05:31.19\00:05:33.16
at different rates.
00:05:33.26\00:05:34.73
Some have half lives of seconds.
00:05:34.83\00:05:37.30
Others decay much more slowly.
00:05:37.40\00:05:39.53
But of course, no one
has watched Uranium-238
00:05:39.63\00:05:42.67
for four billion years.
00:05:42.77\00:05:44.24
That would be a very boring job.
00:05:44.34\00:05:46.24
So the rate is calculated
from the small sample of time.
00:05:46.34\00:05:49.94
You can't measure
a radiometric date
00:05:50.05\00:05:52.21
like you can
measure the mass of a rock.
00:05:52.31\00:05:54.28
You have to calculate it.
00:05:54.38\00:05:55.88
And that calculation
only gives you the right date
00:05:55.98\00:05:58.42
if the assumptions are true.
00:05:58.52\00:06:00.76
There are three
basic assumptions
00:06:00.86\00:06:02.46
used when
calculating a radiometric date.
00:06:02.56\00:06:05.83
The first
assumption is that there
00:06:05.93\00:06:07.36
was none of the daughter element
in the rock to begin with.
00:06:07.46\00:06:10.97
For example, you have to assume
that no lead was in the rock
00:06:11.07\00:06:14.64
when it was formed to use
the uranium-lead dating method.
00:06:14.74\00:06:18.04
But how would a
scientist know this?
00:06:18.14\00:06:20.21
They can't.
00:06:20.31\00:06:21.31
That's why it's a
faulty assumption.
00:06:21.41\00:06:24.15
The second assumption is
that the radioactive element
00:06:24.25\00:06:26.82
decays at a constant rate.
00:06:26.92\00:06:28.45
The rate was not
faster or slower in the past.
00:06:28.55\00:06:31.99
That is the
uniformitarianism concept again.
00:06:32.09\00:06:35.39
Yet, the Bible teaches
something much different.
00:06:35.49\00:06:37.73
The Earth has gone
through a huge catastrophe,
00:06:37.83\00:06:40.83
the global flood.
00:06:40.93\00:06:43.10
In addition,
this second assumption
00:06:43.20\00:06:44.93
does not take into account heat,
or pressure, or other forces
00:06:45.03\00:06:49.07
that might have had
an influence in the decay
00:06:49.17\00:06:51.21
rate of an element.
00:06:51.31\00:06:52.64
In some instances, we can
observe radioactive decay rates
00:06:52.74\00:06:55.78
changing drastically.
00:06:55.88\00:06:57.81
The third assumption is
that the elements in the rock
00:06:57.91\00:07:00.38
operated in a closed system.
00:07:00.48\00:07:03.08
In other words, there
were no outside influences
00:07:03.18\00:07:06.05
on the parent or
daughter elements, no addition
00:07:06.15\00:07:09.29
or removal of
uranium or lead, which
00:07:09.39\00:07:12.43
is a big assumption considering
that the rock has supposed
00:07:12.53\00:07:15.86
to have been around
for millions of years.
00:07:15.96\00:07:19.20
If there was any
contamination, then
00:07:19.30\00:07:21.57
all bets are off on
having a good sample
00:07:21.67\00:07:23.94
to calculate
the age of the rock.
00:07:24.04\00:07:26.37
For those who
believe in long ages,
00:07:26.47\00:07:28.58
these assumptions are
critical to their beliefs.
00:07:28.68\00:07:31.25
While there are
methods to get around
00:07:31.35\00:07:32.95
some of these
assumptions in some cases,
00:07:33.05\00:07:35.75
any breakdown in
these assumptions
00:07:35.85\00:07:37.92
would lead to a total
meltdown of the arguments
00:07:38.02\00:07:40.56
based on radiometric dating.
00:07:40.66\00:07:43.06
The RATE group decided to take
a fresh look at this subject
00:07:43.16\00:07:46.63
and see what they
could learn without being
00:07:46.73\00:07:48.96
forced to stick to the
uniformitarian assumptions.
00:07:49.06\00:07:52.53
They wanted to know
if the rate of decay
00:07:52.63\00:07:54.80
had been different in
the past due to catastrophic
00:07:54.90\00:07:57.51
geologic processes
during the global flood.
00:07:57.61\00:08:00.94
They also looked at the
issue of the daughter elements
00:08:01.04\00:08:03.78
to see if they were in the
rocks from the beginning, which
00:08:03.88\00:08:06.82
would throw a monkey
wrench in the calculations
00:08:06.92\00:08:09.42
for the dating of these rocks.
00:08:09.52\00:08:11.99
Third, they intentionally
looked for evidence
00:08:12.09\00:08:14.72
that radioactive processes
had produced accelerated decay.
00:08:14.82\00:08:18.66
They begin their
research by collecting over
00:08:18.76\00:08:20.83
1,000 rock samples
from all over the world,
00:08:20.93\00:08:23.90
including Yosemite Valley.
00:08:24.00\00:08:26.27
When some
radioactive elements decay,
00:08:26.37\00:08:28.54
in addition to
producing the daughter element,
00:08:28.64\00:08:31.01
alpha particles are
thrown off from the parent
00:08:31.11\00:08:33.54
as it changes into the new
element, such as polonium-210,
00:08:33.64\00:08:37.91
also known as radium F.
00:08:38.01\00:08:40.22
We can see this decay
in the form of radiohalos.
00:08:40.32\00:08:44.52
Radiohalos are the damage
left by the emission of some
00:08:44.62\00:08:47.76
of these alpha
particles captured
00:08:47.86\00:08:49.39
in the surrounding
rock during the decay
00:08:49.49\00:08:51.29
series of uranium-238.
00:08:51.39\00:08:53.73
As I said, the
half-life of uranium-238
00:08:53.83\00:08:57.30
is supposed to be 4.468
billion years to arrive at lead.
00:08:57.40\00:09:02.20
But the
different types of polonium
00:09:02.30\00:09:04.27
only have half-lives of
164 seconds, 3.1 minutes,
00:09:04.37\00:09:09.08
and 138 days.
00:09:09.18\00:09:11.48
If the crystals
in the granite rocks
00:09:11.58\00:09:13.62
cooled slowly over millions
of years or even one year,
00:09:13.72\00:09:17.35
the radiohalos
from the polonium would
00:09:17.45\00:09:19.52
have reached the end of
their life and disappeared.
00:09:19.62\00:09:22.49
When the rocks from
Yosemite were studied,
00:09:22.59\00:09:25.09
the most bizarre
thing was discovered.
00:09:25.19\00:09:27.66
Polonium halos were
found frozen in the rocks.
00:09:27.76\00:09:31.43
The fact that we see
any radiohalos from polonium
00:09:31.53\00:09:34.80
is good
evidence that these rocks
00:09:34.90\00:09:36.64
cooled very, very
quickly, fast enough
00:09:36.74\00:09:39.51
to capture what the
damage had done to the crystals
00:09:39.61\00:09:42.18
before the
polonium all turned to lead.
00:09:42.28\00:09:45.51
It is believed by
secular scientists
00:09:45.61\00:09:47.65
that the granite
in the Sierra Nevada
00:09:47.75\00:09:49.65
was formed slowly
over millions of years.
00:09:49.75\00:09:52.45
But the fact that the polonium
radiohalos are found especially
00:09:52.55\00:09:56.49
in abundance in all
the granitic rock layers
00:09:56.59\00:09:59.53
means something much different
than slow, gradual processes.
00:09:59.63\00:10:03.93
With the right
conditions during the Flood,
00:10:04.03\00:10:06.37
the entire pluton,
or mass of igneous rock,
00:10:06.47\00:10:09.44
could have formed
very quickly, maybe even
00:10:09.54\00:10:11.57
within a couple of weeks.
00:10:11.67\00:10:13.11
This massive
catastrophic process
00:10:13.21\00:10:15.68
would have contributed greatly
to the accelerated decay rate.
00:10:15.78\00:10:19.71
As the flood waters receded,
due to the continents rising
00:10:19.81\00:10:23.05
and the sea floor
sinking, the Sierras
00:10:23.15\00:10:25.29
were uplifted to
their current position,
00:10:25.39\00:10:27.26
likely in a matter of months.
00:10:27.36\00:10:29.52
The flood was
quick and catastrophic,
00:10:29.62\00:10:32.19
just as the Bible says.
00:10:32.29\00:10:33.83
It didn't take
millions and billions of years
00:10:33.93\00:10:36.53
to form these
rocks that we see today.
00:10:36.63\00:10:38.60
Science, it's awesome.
00:10:38.70\00:10:40.44
As you enter
through Yosemite Valley,
00:10:46.34\00:10:48.71
the granite cliffs
rising above 3,000 feet
00:10:48.81\00:10:52.15
impress the viewer
with the grandeur of God.
00:10:52.25\00:10:56.58
From Glacier Point, a visitor
can view Yosemite Valley below.
00:10:56.69\00:11:00.66
Without question,
something big cut this valley.
00:11:00.76\00:11:04.69
Secular scientists claim that as
the mountains were being pushed
00:11:04.79\00:11:07.66
up over millions of
years, the Merced River
00:11:07.76\00:11:10.40
flowed a little bit
faster and cut this valley.
00:11:10.50\00:11:13.44
Yet, it's hard to imagine
this little river cutting
00:11:13.54\00:11:16.00
this huge valley.
00:11:16.10\00:11:17.91
It just doesn't
make sense based on what
00:11:18.01\00:11:20.18
we know about the
principles of erosion.
00:11:20.28\00:11:22.74
There's just not
enough water flow.
00:11:22.84\00:11:25.65
In addition, what source
was behind the Merced River
00:11:25.75\00:11:28.85
to allow it to
erode this much land?
00:11:28.95\00:11:31.35
It just doesn't
exist, except in the case
00:11:31.45\00:11:34.22
of a massive catastrophe,
such as the global flood.
00:11:34.32\00:11:38.49
In the 1800s, John
Muir explored the park
00:11:38.59\00:11:41.56
and was the first
to hypothesize glaciers
00:11:41.66\00:11:43.87
were involved in
eroding Yosemite.
00:11:43.97\00:11:46.77
It's true that
glaciers cut and smooth
00:11:46.87\00:11:48.94
a valley that already exists.
00:11:49.04\00:11:50.84
But a valley as big as Yosemite
requires something much larger,
00:11:50.94\00:11:55.14
like a global flood.
00:11:55.24\00:11:57.95
Near the end of the
Flood, the continents
00:11:58.05\00:12:00.15
were beginning to rise.
00:12:00.25\00:12:01.85
Mountain chains
were being pushed up.
00:12:01.95\00:12:04.05
And the valleys
were being formed.
00:12:04.15\00:12:06.25
This catastrophic activity
that was moving continents
00:12:06.35\00:12:09.39
subsequently caused
the waters to accumulate
00:12:09.49\00:12:11.99
in the new ocean basins.
00:12:12.09\00:12:13.63
And huge sheet erosion
planed off the new top layers
00:12:13.73\00:12:16.73
of the Earth.
00:12:16.83\00:12:17.90
As there was less water
flowing towards the ocean,
00:12:18.00\00:12:20.67
the erosion continued as
the water flowed in channels,
00:12:20.77\00:12:24.47
cutting giant canyons,
water gaps, and valleys.
00:12:24.57\00:12:29.28
Evidence for this
massive water erosion
00:12:29.38\00:12:31.95
is everywhere on this Earth,
including Yosemite Valley.
00:12:32.05\00:12:35.28
But the erosion of this
famous valley wasn't over yet.
00:12:35.38\00:12:39.39
The Great Ice
Age was to come next.
00:12:39.49\00:12:41.76
And it also left its marks.
00:12:41.86\00:12:43.93
Yosemite is a
testament to the glory of God.
00:12:44.43\00:12:47.50
But it's so much more than that.
00:12:47.60\00:12:49.50
It's a display of quick
and catastrophic processes
00:12:49.60\00:12:52.90
in its formation and erosion
during and after the Flood.
00:12:53.00\00:12:57.54
From the radiohalos to
the quick formation of the Ice
00:12:57.64\00:13:00.44
Age after the Flood
that affected the park,
00:13:00.54\00:13:03.01
the Bible gives us
the best starting point
00:13:03.11\00:13:05.35
to explain the evidence.
00:13:05.45\00:13:07.38
It didn't take
millions of years to form,
00:13:07.48\00:13:09.85
just big events in
a short time period.
00:13:09.95\00:13:12.35
When we use God and His
Word as our history guidebook,
00:13:12.45\00:13:16.22
all that we see in
nature starts to make sense.
00:13:16.32\00:13:19.49
If a secular worldview, which
is based on man's opinions,
00:13:19.59\00:13:22.90
is used, the explanations
of nature will never quite fit.
00:13:23.00\00:13:27.14
That's why the there is
no agreement on how the Ice
00:13:27.24\00:13:30.14
Age developed,
because none of their ideas
00:13:30.24\00:13:32.64
involved the
catastrophic processes as
00:13:32.74\00:13:35.31
described in the Bible.
00:13:35.41\00:13:37.48
When you build a puzzle, you
build the outside edge first.
00:13:37.58\00:13:40.75
Then you work to fit
in the middle pieces.
00:13:40.85\00:13:43.22
In much the same way, we
use the Bible as our frame,
00:13:43.32\00:13:46.25
then begin to fit the
pieces inside together.
00:13:46.35\00:13:49.29
In the end, it all connects
within a coherent and Biblical
00:13:49.39\00:13:52.86
worldview.
00:13:52.96\00:13:54.13
Sure, we don't know
about all the details
00:13:54.23\00:13:56.70
of this world we
live in or its past.
00:13:56.80\00:13:59.47
But we can discover
and learn about God's world
00:13:59.57\00:14:02.87
using His Word.
00:14:02.97\00:14:04.17
That means working to understand
every aspect of this world
00:14:04.27\00:14:08.14
and how it works and
how it is explained best
00:14:08.24\00:14:11.81
by a Biblical worldview.
00:14:11.91\00:14:13.28

We hope you enjoy our great
00:15:03.50\00:15:07.70
content. Standing
over 2,000 feet, these are
00:15:08.80\00:15:11.31
some of the highest
sandstone cliffs in the world.
00:15:11.41\00:15:14.78
The criss-crossing patterns
are due to the layers being
00:15:14.88\00:15:17.61
deposited in flowing water.
00:15:17.71\00:15:19.98
This valley has clear signs
of the sandstone being formed
00:15:20.08\00:15:23.49
by water, then eroded by water.
00:15:23.59\00:15:26.69
Zion includes nine separate
geologic formations thought
00:15:26.79\00:15:30.69
by secular scientists to cover
150 million years of Earth's
00:15:30.79\00:15:34.93
history, yet those
who believe in long ages
00:15:35.00\00:15:38.47
have some major
challenges when trying
00:15:38.57\00:15:40.57
to explain what we see at Zion,
because a proper understanding
00:15:40.67\00:15:44.37
of the evidence
doesn't mesh with their story.
00:15:44.47\00:15:47.04
Instead, astute
researchers recognize
00:15:47.14\00:15:49.81
the catastrophic
formation of the layers
00:15:49.91\00:15:52.15
and the cutting of
this enormous canyon.
00:15:52.25\00:15:54.05
It wasn't millions of
years, but perhaps just weeks.
00:15:54.15\00:15:58.99
Zion is a towering
example of geologic action
00:15:59.09\00:16:02.92
due to the catastrophic
flood action, the Biblical flood
00:16:03.02\00:16:06.06
of Noah's day.
00:16:06.16\00:16:06.93
As one meanders
through the giant canyons,
00:16:10.63\00:16:13.50
the walls of
sandstone are enormous.
00:16:13.60\00:16:16.77
The largest layer is
the Navajo Sandstone, which
00:16:16.87\00:16:19.77
is up to 2,200 feet thick.
00:16:19.87\00:16:23.91
This layer is known to
cover 140,000 square miles
00:16:24.01\00:16:28.42
of the southwest.
00:16:28.52\00:16:29.68
The source of
these sand grains can
00:16:29.78\00:16:31.35
be traced to the
northern Appalachians
00:16:31.45\00:16:33.72
over 1,000 miles away.
00:16:33.82\00:16:36.93
Secular scientists
have suggested several ideas
00:16:37.03\00:16:40.30
on how this sand
moved across the continent.
00:16:40.40\00:16:43.50
One idea is that an
ancient river transported them
00:16:43.60\00:16:46.63
from the
northeast to the southwest,
00:16:46.74\00:16:49.34
but no evidence exists
for this grand waterway.
00:16:49.44\00:16:53.48
Another idea is that they
were blown across by the wind.
00:16:53.58\00:16:57.31
But how did they miss
being deposited in the Midwest
00:16:57.41\00:17:00.25
as well?
00:17:00.35\00:17:01.45
When the details
surface, this idea
00:17:01.55\00:17:03.69
is dashed and
broken against a big wall.
00:17:03.79\00:17:07.12
Without a global flood
model, secular scientists
00:17:07.22\00:17:10.16
have a big
challenge trying to explain
00:17:10.26\00:17:12.49
how these sand grains got here.
00:17:12.59\00:17:14.83
But with worldwide catastrophic
conditions during the Flood,
00:17:14.93\00:17:18.73
the sandstones
are easily explained.
00:17:18.83\00:17:21.60
When sand is blown,
the backside of a dune
00:17:21.70\00:17:24.37
is typically
more than 30 degrees.
00:17:24.47\00:17:26.34
We also know that if water moves
sand, the backside of the dune
00:17:29.11\00:17:32.75
is less than 30 degrees.
00:17:32.85\00:17:36.02
This can be
observed around the world
00:17:36.12\00:17:37.99
and can be tested in the lab.
00:17:38.09\00:17:40.76
Most of the cross-beds
in the Navajo Sandstone
00:17:40.86\00:17:43.69
have angles
less than 30 degrees,
00:17:43.79\00:17:45.93
which we can deduce that
they were moved by water.
00:17:46.03\00:17:49.33
Only one event in Earth's
history would have the water
00:17:49.43\00:17:52.60
and speed to move
140,000 square miles of sand.
00:17:52.70\00:17:57.21
That event was the
global flood of Noah's day.
00:17:57.31\00:18:00.28
When you tour
through Zion Canyon,
00:18:02.98\00:18:05.05
one question
keeps on coming to mind.
00:18:05.15\00:18:07.62
How was it cut?
00:18:07.72\00:18:09.78
Whatever the process
was, it had to work its way
00:18:09.88\00:18:12.79
through thousands
of feet of sediment.
00:18:12.89\00:18:15.19
Secular scientists
attribute the Zion's erosion
00:18:15.29\00:18:18.06
over millions of
years to the Virgin River,
00:18:18.16\00:18:20.46
which flows through
the bottom of the canyon.
00:18:20.56\00:18:23.43
Just a casual
glance at the Virgin River
00:18:23.53\00:18:26.00
shows that it
flows too gradually
00:18:26.10\00:18:28.04
to have caused
this much erosion.
00:18:28.14\00:18:31.74
The river doesn't even
reach the canyon walls.
00:18:31.84\00:18:35.54
What is more,
as one looks deeper
00:18:35.64\00:18:37.75
into the canyon's
features, it becomes evident
00:18:37.85\00:18:40.32
that this canyon was cut in
a very short period of time,
00:18:40.42\00:18:43.55
just days or hours.
00:18:43.65\00:18:45.35
How?
00:18:45.45\00:18:46.15
Let's look a little closer.
00:18:46.25\00:18:47.82
One of the strongest
evidences researchers
00:18:47.92\00:18:50.49
use for a young cut canyon is
how steep the canyon walls are.
00:18:50.59\00:18:54.93
If the canyon was
formed over a long period,
00:18:55.03\00:18:57.80
gravity, erosion,
and other natural forces
00:18:57.90\00:19:00.74
would have
caused these steep walls
00:19:00.84\00:19:02.60
to collapse into the
canyon in various places.
00:19:02.70\00:19:06.41
As a result, this
valley would have been V-shaped
00:19:06.51\00:19:09.18
with lots of debris.
00:19:09.28\00:19:10.98
But there is very
little debris on the canyon
00:19:11.08\00:19:13.72
floor, which is a sign
of a much younger canyon.
00:19:13.82\00:19:18.02
In several
places around the park,
00:19:18.12\00:19:20.22
there are huge arches
high in the canyon walls.
00:19:20.32\00:19:23.83
Arches like these in sandstone
will eventually erode away
00:19:23.93\00:19:27.23
and fall to the canyon floor.
00:19:27.30\00:19:30.13
If the Virgin River
took millions of years
00:19:30.23\00:19:32.30
to carve this
canyon, then these arches
00:19:32.40\00:19:34.70
should have collapsed and
eroded away a long time ago.
00:19:34.80\00:19:38.17
But they are still there.
00:19:38.27\00:19:40.64
In addition, the park
is full of hanging valleys.
00:19:40.74\00:19:44.58
Hanging valleys are formed
when massive amounts of water
00:19:44.68\00:19:47.62
go through an
area at high speeds,
00:19:47.72\00:19:50.05
cutting the landscape
from many different directions,
00:19:50.15\00:19:52.99
generally due to
flooding conditions.
00:19:53.09\00:19:55.26
Some valleys are
higher than others and spill
00:19:55.36\00:19:58.16
into the lower ones.
00:19:58.26\00:20:00.20
When the flood waters
go away, the intersections
00:20:00.30\00:20:03.30
of the upper canyons into the
lower canyons are left hanging.
00:20:03.40\00:20:07.40
Zion is full of these
giant hanging valleys.
00:20:07.50\00:20:11.21
A huge amount of water
moving together at the same time
00:20:11.31\00:20:14.58
would be required to
create these features.
00:20:14.68\00:20:17.51
If small streams
over long periods of time
00:20:17.61\00:20:20.62
were responsible for
carving the hanging valleys,
00:20:20.72\00:20:23.42
then they should
have been eroded down
00:20:23.52\00:20:25.49
or be completely
gone, yet they remain
00:20:25.59\00:20:28.92
as a remnant of a global
flood where the receding flood
00:20:29.02\00:20:32.16
waters raced across
the entire continent.
00:20:32.26\00:20:35.30
One of the features in the park
that secular scientists point
00:20:35.40\00:20:38.63
to as evidence for
slow and gradual erosion
00:20:38.73\00:20:41.27
by the Virgin River is
a place called Big Bend.
00:20:41.37\00:20:44.57
They say that if catastrophic
processes were at work,
00:20:44.67\00:20:48.21
this feature would
have been eroded away.
00:20:48.31\00:20:51.98
We know that when flowing
water finds an obstruction,
00:20:52.08\00:20:55.18
it usually
finds a way around it.
00:20:55.28\00:20:57.62
Obstructions
will usually be harder
00:20:57.72\00:20:59.65
than the layer being eroded.
00:20:59.75\00:21:01.86
The water finds a
weaker point and goes that way.
00:21:01.96\00:21:05.66
This is exactly what
happened in Big Bend.
00:21:05.76\00:21:08.43
And this is
consistent with a Biblical view.
00:21:08.53\00:21:11.40
You can make this simple
observation at the beach.
00:21:11.50\00:21:14.80
Watch how receding
waves cut the sand.
00:21:14.90\00:21:17.47
Most of the time, they
don't go in a straight line
00:21:17.57\00:21:20.21
but find the
weakest point in the sand.
00:21:20.31\00:21:22.78
With all of these observable
facts, the amount of water
00:21:22.88\00:21:26.11
and the speed of the
water needed to cut Zion,
00:21:26.21\00:21:28.92
it is a testament to
the flood of Noah's day.
00:21:29.02\00:21:32.79
After covering the
entire Earth by day 150,
00:21:32.89\00:21:36.36
the flood waters were receding.
00:21:36.46\00:21:38.66
As the continents rose
and the ocean valleys sank,
00:21:38.76\00:21:41.63
water ran off the
continents, first in sheets.
00:21:41.73\00:21:45.13
Then it began to channelize.
00:21:45.23\00:21:47.44
When the water finally
emptied into the oceans,
00:21:47.54\00:21:50.11
it left these canyons.
00:21:50.21\00:21:52.81
This whole area in the
southwest is full of large scale
00:21:52.91\00:21:56.78
erosional features.
00:21:56.88\00:21:58.65
Secular scientists
have had a difficult time
00:21:58.75\00:22:01.12
explaining all of
these features through
00:22:01.22\00:22:03.18
slow and gradual processes.
00:22:03.28\00:22:05.89
The global flood best
explains what we see here
00:22:05.99\00:22:08.72
at Zion and at many
other geologic features
00:22:08.82\00:22:12.23
around the world.
00:22:12.33\00:22:14.36
The Biblical
record can be trusted.
00:22:14.46\00:22:16.97
As we look at
the geologic record,
00:22:17.07\00:22:18.87
the evidence
starts to make sense
00:22:18.97\00:22:20.87
when you include a
catastrophic global flood
00:22:20.97\00:22:23.67
as described in the
Bible as a real historic event.
00:22:23.77\00:22:26.57
Through our study
of the canyon, it's
00:22:29.21\00:22:31.05
plain to see that
the Bible's description
00:22:31.15\00:22:33.05
of a
catastrophic flood event best
00:22:33.15\00:22:35.25
explains the formation of these
layers and the erosion at Zion,
00:22:35.35\00:22:39.09
hands down.
00:22:39.19\00:22:41.09
Secular scientists look
at present geologic processes
00:22:41.19\00:22:44.69
and say changes happened
over long ages, like at Zion.
00:22:44.79\00:22:49.00
They hold to those
uniformitarian belief
00:22:49.10\00:22:51.60
because they have a
secular humanist worldview.
00:22:51.70\00:22:55.14
This worldview denies
that there is a God who created
00:22:55.24\00:22:58.71
and who delivers
judgment against sin.
00:22:58.81\00:23:01.48
If man does not have to be
accountable to the Creator,
00:23:01.58\00:23:04.65
then he can live
any way he wants.
00:23:04.75\00:23:07.45
The Bible tells us that it's by
their own actions and thoughts
00:23:07.55\00:23:11.15
that they hold
this world view and deny
00:23:11.25\00:23:13.52
the truth found in God's word,
not because of an unbiased view
00:23:13.62\00:23:17.53
of the evidence.
00:23:17.63\00:23:19.33
We can view the
evidence starting with the truth
00:23:19.43\00:23:22.23
of what the Bible says.
00:23:22.33\00:23:23.83
And it matches up with
quick, catastrophic events.
00:23:23.93\00:23:27.37
Zion shows God's great handiwork
but also His judgement.
00:23:27.47\00:23:32.64
The Bible tells us
that the global flood
00:23:32.74\00:23:34.94
was brought by
God because of man's
00:23:35.04\00:23:37.11
rebellion against his Creator.
00:23:37.21\00:23:38.91
Only one man was
found righteous, Noah.
00:23:39.01\00:23:42.08
And he and his
family were saved.
00:23:42.18\00:23:43.95
Notice the grace of God.
00:23:44.05\00:23:45.95
He sent a means of
salvation through the ark.
00:23:46.05\00:23:48.89
The Flood was real.
00:23:48.99\00:23:50.69
The Bible can be believed.
00:23:50.79\00:23:53.66
But there's also a
warning to all of us.
00:23:53.76\00:23:56.87
God's judgment is coming
again, this time by fire.
00:23:56.97\00:24:01.64
Man had over 100
years before the flood
00:24:01.74\00:24:04.54
to turn and
repent of his rebellion.
00:24:04.64\00:24:07.08
God is patient.
00:24:07.18\00:24:08.38
He desires to see all
men repent of their sins
00:24:08.48\00:24:11.51
and turn back to
Him, for God has sent
00:24:11.61\00:24:15.75
another means of salvation.
00:24:15.85\00:24:18.25
If you have not turned
to God through Jesus Christ,
00:24:18.35\00:24:21.29
the Bible says today
is the day of salvation.
00:24:21.39\00:24:24.73
Repent and turn to Him
now before His judgment
00:24:24.83\00:24:27.76
against man's
rebellion comes again.
00:24:27.86\00:24:31.03

Join us next time
as we explore more
00:24:33.50\00:24:35.54
of the Biblical
account of Creation,
00:24:35.64\00:24:37.51
the Fall, and the Flood.
00:24:37.61\00:24:39.21
Science, it's awesome.

We're making a difference
by challenging the deceptive
00:25:11.11\00:25:14.54
evolutionary worldview, which
directly opposes the Word of God
00:25:14.64\00:25:19.05
Our mission is to provide
youth with a firm foundation
00:25:19.05\00:25:22.62
based on solid scientific
evidence that supports their
00:25:22.62\00:25:25.99
Biblical worldview. We
also want to encourage youth
00:25:25.99\00:25:29.72
to pursue the Truth, and maybe
even make a career from their
00:25:29.72\00:25:33.36
interest in
science and the Bible.
00:25:33.36\00:25:35.56
