INFINITY #9: Niagara Falls and the Age of the Earth.
by
Daniel H. Harris, Ph.D.
I. The Questions.
How fast are the continents being worn
away? How fast are the ocean basins filling up? Should we believe that the Earth
is millions and millions of years old? Has there been enough time for evolution
to have produced all the diverse species on planet earth? This INFINITY will
answer these important questions.
II. The Oceans Aren't Filled and the Continents
Still Have Mountains.
The rivers of the Earth each year carry
millions of tons of pulverised rock and organic material into the oceans. Yet
the ocean basins are not filled up, and the continents still have mountains,
hills and elevated plains. So how old are the rivers and oceans?
III. How Old is the Present Mississippi River?
Let's begin with an easy example. The Mississippi
river transports about 300 million cubic yards of sediment into the Gulf of
Mexico each year. When the river reaches the Gulf of Mexico, the river slows,
and its sediment falls out, the result being the Mississippi Delta. The Mississippi
Delta grows larger at a rate of about 250 feet per year. (see ref 1, p163).
If the Mississippi River had flowed for
at least a hundred million years, as is conventionally asssumed, then the Gulf
of Mexico would be full. [see calculation #1 below] But the Gulf of Mexico is
not full, so it is clear that the Mississippi has not flowed for many millions
of years as is conventionally assumed. Using the known size of the Mississippi
Delta and the present rate of its building, the estimated age of the present
Missiissippi Delta is at most 30,000 years.
At the end of the Ice Age, the Mississippi
very likely carried much more sediment each year, than it does today, perhaps
ten to thirty times as much as it does today. Thus the 30,000 year age of the
Mississippi Delta, is an upper limit on the age of the Mississippi River. So
it is reasonable to suppose that the Mississippi has followed in its present
channel for less than 10,000 years, an estimate being 3,000 to 6,000 years.
IV. The Mississippi River During the Ice Age.
So, if the Mississippi has been in its
present channel such a short time, then what was going on before that? Before
that time, presumably the Mississippi was flowing in a different channel. Perhaps
a major earthquake or some other disturbance, moved the Mississippi from that
earlier channel into its present channel.
To discover the location of its previous
channel, we can look for its previous delta on the margins of the Gulf of Mexico.
Maps of the Gulf of Mexico show that out in the gulf, at a depth of about 1000
feet, the gulf floor is not so steeply sloping south of Lake Charles and New
Iberia, Louisiana. Which is about 100 miles west of the Mississippi's present
channel and delta. This is likely where the old Mississippi flowed into the
Gulf of Mexico, during the Ice Age. The old Mississippi Delta, can be seen at
a depth of about 1000 feet, because sea levels were lower when the continents
were covered by ice sheets.
V. A Young Mississippi Rivier.
Even this larger delta of the old Mississippi,
would only take thousands of years to form, not millions. This shows that the
old Mississippi and the present Mississippi, together are perhaps at most fifteen
thousand years old. For the Mississippi to be more that one
hundred million years old, as is conventionally supposed, its average load of
sediment carried to the gulf each year would have to be perhaps a factor of
3000 times less than its average sediment load is today. This would require
us to suppose that in the past the Mississippi was not a major river, that the
Mississippi has only recently become a major river, which is not a reasonable
supposition. Therefore, it is unreasonable to suppose that the Mississippi River
is many millions of years old as is generally supposed.
VI. The Age of the Niagra River and Niagra
Falls.
Anyone who has visited Niagara Falls, probably
knows that the water flowing over the falls, wears away the rocks, and that
the falls are moving up stream. The French explorer Hennepin first mapped the
falls in 1678 (ref. 1, p175). From that time until 1842 the falls retreated
at an average rate of about seven feet per year. #9;More recently the falls have retreated
at a rate of about three and a half feet per year. The present gorge of the
Niagara is about seven miles long. If the average rate of retreat is seven feet
per year, then the falls are only about 5,000 years old. If the average rate
of retreat is three and a half feet per year, as it is at present, then the
falls are about 10,000 years old.
The Niagara has flowed in its present channel
only since the Ice Age. During the Ice Age, the whole area was covered with
a thick layer of ice. When the Niagara began to follow in its present channel
at the end of the Ice Age, it very likely had a much greater volume of swiftly
moving water. The falls would have been rapidly retreating. So a reasonable
estimate of the time since the Ice Age would be 3 to 6 thousand years. That's
about the time, when the Mississippi moved from its old channel into its present
channel. So, the numbers seem to agree [within the large uncertainties involved].
The volume of sediments deposited in deltas and the rate of river erosion would
suggest that these processes have been going on only for thousands or tens of
thousands of years. So how could it be that the rivers ar so young? Let's look
at the big picture.
VII. Filling Up The Ocean Basins With Sediment.
Each year moving water from the continents
carries about 28 billion tons of pulverized rock, and organic material, into
the earth's seas and oceans (ref. 1 , p166). But the mountains and plains haven't
worn away and the oceans basins are not yet full.
The present thickness of sediment on the
ocean floors averages about 1500 feet (450 meters) thick. If this accumulation
of ocean floor sediment were the result only of the water born sediments carried
by rivers off of the continents, then it would take at most about 9 million
years to accumulate the present layer of deposits. [See Calculation #2]
VIII. Biological Activity Adds To the Sediments.
But we know that in the oceans, microscopic
creatures make shells, and these rain down on the ocean floor. On the ocean
floor other organisms extract minerals from the water, also making deposits.
The excrement and the decay products of fish and other marine animals, also
rain down onto the ocean floor.
Recent photos of the wreck of the Titanic
show a thick layer of deposits on the hand rails, decking and other exposed
surfaces. In less that 100 years about 2/3 of an inch of deposits formed. A
similar rate of activity on the ocean basins in general permits the ocean floor
sediments to accumulate in only about 3 million years. [See calculation #3]
IX. Greater Biological Activity In the Ancient
Oceans.
But the Earth's present oceans are much
less biologically active than they were in the past. There is good reason to
believe that in the past, ocean temperatures were higher, and the pressure of
disolved gases in the oceans was greater, and biological activity was much greater,
accumulating ocean floor deposits much more rapidly than today.
[Geologists tell us that in the Mesozoic
Era, there were tropical forrests in Alaska, Siberia, Antarctica and Australia,
and the Earth's average temperature was tropical at all latitudes. And flying
insects were much larger then than they are today [see INFINTY #3] showing that
the atmosphere was much thicker then than it is today.] With greater biological activity in the
ancient oceans, the 1500 feet of ocean floor deposits could accumulate in less
than a million years. Regardless of the details of our calculations, the oceans
seem to be at most a few million years old, and this tells us that the Earth
is young.
X. Evolution Needs Time, And There Isn't Enough.
The advocates of evolution tell us that
it took many hundreds of millions of years for fish to become amphibians, and
then reptiles, and so forth. And the advocates of evolution tell us that the
oceans are at least two billon years old. In that amount of time the continents
would have worn away, and the ocean basins filled at least two hundred times.
But there is no evidince to suggest that the ocean basins have been filled even
once, let alone hundreds of times, as the evolutionary time scales require.
Thus the facts of ocean floor deposition do not agree with the necessary long
ages needed for evolution to do its magic.
Invariable laboratory studies have failed
to find evolution. Therefore, the advocates of evolution say that
evolution happens very slowly, so slowly that it can't be seen in the laboratory.
So the evolutionists say that long ages, hundreds of millions of years are necessary
for evolution to produce the life we see on planet earth. But the evidence of
the oceans tells us that the earth is too young for this to have occurred.
XI. Ocean Sediments on Top of Mountains!
On the continents, even near the top of
Mt. Everest, are many deposits of sedimentary rocks, which were no doubt laid
down in water. The most abundant fossils found in these continental sedimentary
rocks are the fossils of sea creatures with shells, called marine invertibrates.
To explain this, the supporters of evolution
suppose that the continents have dipped below sea level and then reemerged many
many times over many hundreds of millions of years.
By contrast the advocates of creation often
explain the marine sediments on the continents and high mountains, as evidence
of one catastrophic world wide flood.
XII. The Simplest Hypothesis.
When explaining phenomena, scientists generally
assert that they prefer the simpler explanation [Ockham's razor]. So which is
simpler, a process that moves whole continents up and down many times over hundreds
of millions of years; or a process which just once covers the land with water,
making all the marine deposits in one major event? Clearly, the latter hypothesis
is simpler and therefore more reasonable, because one event explains many phenomena.
This one world wide catastrophic flood
sounds very much like the flood in the days of Noah, described in Genesis, and
in the traditions of over three hundred people-groups around the world. How
is it that these widely scattered peoples all have similar legends of the world
wide catastrophic flood? How is it that many of these legends agree that the
flood was a judgement of God against wicked mankind? Perhaps we should recognize
that the marine fossils on the high mountans, and the traditions of many peoples
are in agreement in describing an event that really did happen, which really
was a judgement of God.
XIII. Flood Deposites Cut The Earth's Age.
If the abundant marine fossils found on
all the continents, are indeed the result of a world wide catastrophic flood
in Noah's time, then runoff from the continents into the oceans soon after the
flood may account for much of the 1500 feet of ocean floor sediments we see
today. In that case, the upper limit on the age of the oceans drops dramatically,
coming down to less than about thirty thousand years.
XIV. Abundant Species Not by Evolution, But
by Creation.
And if the oceans are only thousands of
years old, then we can surmise that the Earth is indeed a young planet, and
that evolution has not had time to occur. And since evolution has not
had time to occur, the wide variety of plants and animals we see today didn't
arise by means of evolution. The abundant varieties must have been created,
not long ago, appearing much as they do today.
XV. So There Must Be a Creator!
And if these abundant varieties were created,
then there must be a creator, a creator wise enough to make all the present
varieties, and many more that are now extinct, that have been found buried in
the rocks as fossils. This deduction of the existence of a wise creator God
arises from a variety of investigations [see INFINITY #2, #4, & #6]
XVI. The Creator Who Is Judge.
This wise creator God is also a righteous
judge, for we see in the world wide catastrophic flood, that judgement will
fall when God's creation refuses to obey. So if the creator is also judge, then
we should fear this great God, who has the power to create and the power to
destroy. We should be committed to seeking fellowship with this creator God,
that we might learn to obeying His soverign will.
XVII. The Best Science Agrees With the Holy
Bible!
Sir Francis Bacon, early proponent of the
scientific method, instructs us that the first principle of the scientific method
is to clear our minds of all prejudices. So let us imagine what it would be
like if we had no knowledge whatever of geology and the supposed age of the
Earth. Suppose with a mind thus cleared of prejudice, you were to pick up the
Holy Bible and read the early chapters of Genesis. You would surely suppose
from an unbiased reading of the text, and a study of the Hebrew words, that
the universe and the Earth are perhaps 6 thousand to 15 thousand years old.
This would be the simplest possible reading of the text. [Thus applying Ockham's
razor, the simplicity test, to the reading of these passages, we read the word
"day" to mean "day," not complicating the matter.] Even if there were many missing generations
in the lists given in the Book of Genesis, the age of the Earth can't be millions
of years. Thus we see that the age of the Earth given by the best science agrees
with the age of the Earth seen in an unbiased reading of Genesis!
Even the New Testament tells us that the
Earth is young. In Romans 9:28, the Apostle Paul writes that: "... a short work
will the Lord make upon the Earth." So, if God completes the work of establishing
the Kingdom of God on Earth, in less than 15 thousand years, then the Lord is
indeed doing a quick work.
XVIII. So Why Do Scientists Say the Earth is
Old?
So if the evidence is so clear that the
Earth is young, and that the flood was world wide and catastrophic, then how
is it that many scientists suppose that the Earth is old, and the fossils were
not made in the flood?
You must understand the mind set of scientists.
Scientists are trained to do difficult and complicated things, so they are accustomed
to thinking in terms of the complicated and difficult, and so scientists
suppose that any really important truth must be complicated and difficult.
If the truth is simple, as it often is, then the truth can be missed, as Newton's
laws of motion were missed for more than two thousand years.
If the Earth is billions of years old,
then the study of its history becomes difficult and complicated, requiring many
man-hours and many scientists, as scientists would expect. But if the Earth
is only thousands of years old, then things are much simpler than the scientists
can imagine.
Most scientists at some time dream of making
the great discovery, a new wide reaching principle; and they see the work of
scientists as the source of progress and true wisdom. Scientists are always
looking forward to the latest technology, the newest discovery, not imagining
that the deepest truth of all might be found in a very old book gathering dust
on their book shelf.
XIX. The Warning Of Jesus.
If we listen to the words of Jesus regarding
scholars and truth, in Matt. 11:25, we read, "I thank thee, O Father, Lord of
heaven and earth, because thou hast hid these things [great truths] from the
wise and prudent [the scholars], and hast revealed them unto babes [see also
Psm. 8:2]." God has made the most profound truths so simple, that those that
think themselves wise, see themselves as knowing better than God and so thay
are unable to believe God's simple truths. Jesus reaffirms this when He
says in Mark 10:15, "Whosoever shall not receive [the truth of] the kingdom
of God as a little child, he shall not enter therein." Simplicity-humility is
one of the keys to true understanding. But scholars and scientists too often
suppose that truth can't be simple, and so they miss simple truth.
XX. The Creator Speaks!
As a scientist and as a Christian, I [Dr.
Harris] have been often pleased to discover that the best science agrees with
the testimony of the Holy Bible. In my researches I have tested the Scriptures
many times, and it has always lead me into a better understanding of the world
around me. I am now very comfortable trusting in the truth of God's Word, the
Holy Bible. In fact I depend heavily on revelation arising from the Holy Bible
to gain insights into the nature of the universe, the laws of space and time,
and the behavior of matter within the universe.
[In my walk with the Lord Jesus Christ
I have found that it is much wiser to permit revelations from the Word of God
to inform the meaning of science, than it is to permit science to inform the
meaning of the Word of God!]
Yes, nature is revealed in the Scriptures,
but what is more important, the creator is revealed in the Scriptures, the creator
who is a righteous judge, who should rightly be feared, for He has the power
to create and to destroy.
The Holy Scriptures throughout, bear witness
to the one true God, who's name is Jesus, the one who inspired & directed
the writing of the Holy Bible, and who created the universe. This good and wise
creator God speaks to His created beings through His writen words, informing
us of His nature and of the character of His creation, and of our need for Him.
The Scriptures tell us that in self-will and rebillion we have all become alienated
from fellowship with Him, and that we need restoration.
Because it is wise to fear the God who
creates and destroys, it is also wise to search the words of this creator God
for God's way of dealing with the human condition. So I invite you to look into
the matter, to follow after the one true Go,d and in so doing put your trust
in Him, and the Holy Bible which He gave us. To do so please see Click here for release to Christ.
Calculation #1. Approximating the Gulf of Mexico as a rectangle 860 miles long, by 380 miles wide gives an area for the Gulf of Mexico of approximately 1.0 x 1012 square yards [8.5 x 1011 m2], and then multiplying by an approximate average depth of 4,500 yards [4100 m] gives an approximate volume is 4.5 x 1015 cubic yards [3.5 x 1015 m3]. The rate of inflow from the Mississippi is approximately 300 million cubic yards/year at present. If the Mississippi were flowing at its present rate, in its present channel, and if the Mississippi were the only river flowing into the Gulf of Mexico, the Mississippi alone would fill the Gulf of Mexico in about 15 million years. But the Mississipi is not the only river carrying sediment into the Gulf of Mexico, and shortly after the Ice Age the sediment load of the Mississippi must have been much greater than it is today. Therefore, a reasonable upper limit on the age of the Gulf of Mexico and the Mississippi is perhaps the estimated two million years needed to fill the Gulf of Mexico.
Taking the Delta of the MIssissippi to be a triangle with a base of 120 miles, and a height of 113 miles, gives a area of 2.1 x 1010 yd2 [or about 1.8 x 1010 m3]. And using an average depth of fill of 400 yds [366m] gives a total volume of 8.4 x 1012 yds3 [6.4 x 1012 m3], which at a present rate of 300 million cubic yards/year gives a time to make the Mississippi Delta of 28,000 years. But in the time immediately after the Ice Age the sediment load would have been much greater. Thus a reasonable estimate of the age of the Mississippi Delta is five to ten thousand years.
Calculation #2. The area of earth is 5.1 x 1014 m2. The area of the ocean floor is about 65% of that area, or about 3.3 x 1014 m2. A layer 450 meters thick (1500 feet) gives a volume of 1.5 x 1017 m3. With a present inflow rate of approximately 1.7 x 1010 meters3/yr of deposits coming from off the continents, we get time of 9 million years to accumulate all the sediment on the ocean floor. In such a short time the effects of continental movements, such as subduction and mountain building can be neglected.
Calculation #3. If we conservatively estimate that biological deposition accumulates about 1.0 cm/100yr of sediments on the ocean floor, then to accumulate a 450 meter thick layer takes only about 4.5 million years. If both sediment inflow and biological activity work together at their present rate, then the time needed to accumulate 450 m of ocean floor sediements is perhaps 3 million years.
