The
Earth, with its atmosphere and oceans, its complex
biosphere, its crust of relatively oxidised, silica
rich, sedimentary, igneous, and metamorphic rocks
overlaying [a magnesium silicate mantle and core]
of metallic iron, with its ice caps, deserts,
forests, tundra, jungles, grasslands, fresh-water
lakes, coal beds, oil deposits, volcanoes, fumaroles,
factories, automobiles, plants, animals, magnetic
field, ionosphere, mid-ocean ridges, convincing
mantle... is a system of stunning complexity.

An imaginary space-traveler approaching
the solar system from interstellar space would
encounter a very interesting scene. Let us imagine
that we are such travelers and that we're arriving
at the plane of the ecliptic–the great circle
of the celestial sphere in which all the major
planets of our solar system move. The first planet
we will meet is Pluto. This planet is quite a
cold place. The temperature is around -238°C.
The planet has a thin of atmosphere that is in
a gaseous state only when it draws slightly nearer
to the sun in its rather elliptical orbit. At
other times, the atmosphere becomes a mass of
ice. Pluto, briefly, is a lifeless sphere enveloped
in ice.
Advancing towards
the sun, you next encounter Neptune. It is cold
too: approximately -218°C. The atmosphere, consisting
of hydrogen, helium and methane, is poisonous
for life. Winds blowing nearly 2,000 kilometers
an hour blast across the surface of the planet.

Allah created the heavens and the earth
with truth. There is certainly a Sign
in that for the believers.
(Surat al-Ankabut: 44)

Next is Uranus:
a gaseous planet with rocks and ice on its surface.
The temperature is -214°C and the atmosphere again
consists of hydrogen, helium and methane-–unsuitable
for human beings to live in. You
reach Saturn after Uranus. This is the second
biggest planet in the solar system and is particularly
notable for the system of rings encircling it.
These rings are made up of gases, rock and ice.
One of the many interesting things about Saturn
is that it is composed entirely of gas: 75% hydrogen
and 25% helium and its density is less than that
of water. If you want to "land" on Saturn, you'd
better design your spaceship to be like an inflatable
boat! The average temperature is again very low:
-178°C.
Coming up next
is Jupiter: the biggest planet in the solar system,
it is 318 times the size of Earth. Like Saturn,
Jupiter is also a gaseous planet. Since it is
difficult to distinguish between "atmosphere"
and "surface" on such planets, it is hard to say
what the "surface temperature" is but in the upper
reaches of the atmosphere, the temperature is
-143°C. A notable feature of Jupiter's atmosphere
is something called the Great Red Spot. It was
first noticed 300 hundred years ago. Astronomers
now know that it is an enormous storm system that
has been raging in the Jovian atmosphere for centuries.
It is big enough to swallow up a couple of planets
the size of Earth whole. Jupiter may be a visually
thrilling planet, but it's no home for people,
who would be killed instantly by its freezing
temperatures, violent winds, and intense radiation.
Then comes Mars.
The atmosphere of Mars cannot sustain human life
because it is mostly carbon dioxide. The surface
is everywhere pocked with craters: the result
of eons of meteor impacts and strong winds blowing
across the surface that can raise sandstorms that
last for days or weeks at a time. The temperature
varies rather much but drops as low as -53°C.
There has been much speculation that Mars might
harbor life, but all the evidence shows that this
is a lifeless world too.
Speeding away
from Mars and heading toward the sun, we notice
a blue planet that we decide to skip for the time
being while we explore some more. Our search brings
us to a planet called Venus. This planet is everywhere
shrouded in brilliant white clouds but the temperature
at the surface is 450°C, which is enough to cause
lead to melt. The atmosphere is composed mostly
of carbon dioxide. At the surface, the atmospheric
pressure is equal to 90 terrestrial atmospheres:
on Earth, you'd have to descend a kilometer into
the sea before you reached a pressure that high.
The atmosphere of Venus contains layers of gaseous
sulfuric acid several kilometers deep. When it
rains on Venus, it isn't raining rain you know:
it's raining acid. No human or other life could
exist in such a hellish place for a second.
We press
on and come to Mercury, a small, rocky world,
blasted by the heat and radiation of the sun.
Its rotation has been so slowed down by its proximity
to the sun that the planet makes only three full
axial rotations in the time it takes to revolve
twice around the sun. In other words, two of Mercury's
"years" is equal to three of its "days". Because
of this prolonged diurnal cycle, one side of Mercury
becomes extremely hot while the other is extremely
cold. The difference between the daytime and nighttime
sides of Mercury is as much as 1,000°C. Of course
such an environment cannot support life.

Even Mars, the only other planet in the
solar system to come close to resembling
the earth physically, is nothing but an
arid, lifeless ball of rock.
|
ything that might
serve as a haven for life. Each of them is lifeless
ball of gas, ice, or rock.
But the blue
planet that we skipped over a while ago? That
one's very different from the others. With its
hospitable atmosphere, surface features, ambient
temperatures, magnetic field, and supply of elements
and set just the right distance from the sun,
it almost seems as if it had been specially created
to be a home for life.
And, as we shall discover, it was.
| THE
INFERNAL SURFACE OF VENUS
The
surface temperature on Venus reaches as
high as 450° C, which is sufficient to
melt lead. The surface of this world resembles
a ball of fire covered with lava. Its
atmosphere is thick with sulfuric acid
and a sulfuric acid rain falls constantly.
The atmospheric pressure at the surface
is 90 times that of Earth: the equivalent
of a depth of 1,000 meters beneath the
sea. |

A Brief Digression and Warning About "Adaptation"
In the
rest of this chapter we will be examining features
of Earth that make it clear that our planet was
created specifically for the support of life.
But before we do that, we need to make a brief
digression in order to avoid the possibility of
any misunderstanding. This digression is especially
for those who are in the habit of recognizing
the theory of evolution as a scientific truth
and who strongly believe in the concept of "adaptation".
"Adaptation"
is the noun form of the verb "adapt". "Adapt"
implies a modification according to changing circumstances.
As used by evolutionists, it means a "modification
of an organism or its parts that makes it more
fit for existence under the conditions of its
environment". The theory of evolution claims that
all life on earth is derived from a single organism
(a single common ancestor) that itself came into
being as a result of chance and the theory makes
heavy use of this sense of the word "adaptation"
to support its case. Evolutionists hold that living
organisms change into new species by adapting
to their environment. We have discussed the invalidity
of this claim, that mechanisms of adaptation to
natural conditions in living beings come into
play only under certain circumstances and it can
never transform one species into another in detail
in our other books.2 (This is summed up in the
appendix "Evolution Deceit" in this book) The
theory of evolution with its concept of "adaptation"
is really just a form of Lamarckism, a theory
of organic evolution that holds that environmental
changes cause structural changes in animals and
plants that can be transmitted to offspring- a
theory that has been soundly and rightly dismissed
by scientific circles.
Yet even though
it has no scientific basis, the idea of adaptation
impresses most people and that is why we must
address this point here before going on. From
belief in the adaptability of life-forms, it is
only a step to the idea that life could have developed
on other planets as well as it did once on Earth.
The possibility of little green creatures living
on Pluto who might work up a slight sweat when
the temperature soared to 238°C, who breathe helium
instead of oxygen, and who drink sulfuric acid
instead of water somehow tickles people's fancy,
especially people whose fancies have been richly
nourished by the products of Hollywood studios.
But these are
only such stuff as dreams (and Hollywood movies)
are made of however and evolutionists who are
better informed about biology and biochemistry
do not even attempt to defend such notions. They
know quite well that life exists only if necessary
conditions and elements are available. If they
really believe in them at all, the partisans of
the little green men (or other alien life-forms)
are those who blindly adhere to the theory of
evolution and are ignorant of even the basics
of biology and biochemistry and who, in their
ignorance, come up with preposterous scenarios.
So in understanding
the error in the concept of adaptation, the first
thing that we need to note is that life
can only exist if certain essential conditions
and elements are present. The only model
of life that is based on scientific criteria is
that of carbon-based life and
scientists are in agreement that there is no other
form of life to be found anywhere elsewhere in
the universe.
Carbon is the
sixth element in the periodic table. This atom
is the basis of life on earth because all organic
molecules (such as nucleic acids, amino acids,
proteins, fats, and sugars) are formed by the
combination of carbon with other elements in various
ways. Carbon forms millions of different types
of proteins by combining with hydrogen, oxygen,
and nitrogen etc. No other elements can take the
place of carbon. As we shall see in the sections
ahead, no element but carbon has the ability to
form the many different kinds of chemical bonds
on which life depends.
Consequently
if life is going to exist on any planet anywhere
in the universe it is going to have to be
carbon-based.3
There are a number of conditions that are absolutely
essential in order for carbon-based life to exist.
For example, carbon-based organic compounds (like
proteins) can exist only within a certain range
of temperatures. They start to dissociate over
120°C and are irrecoverably damaged if they are
frozen below -20°C. But it is not only temperature
that plays a vital role in determining the allowable
limits of suitable conditions for carbon-based
life to exist: so too do the type and amount of
light, the strength of gravity, the composition
of the atmosphere, and the strength of the magnetic
field. Earth provides precisely such conditions
as are needed to make life possible. If even one
of conditions were to be changed, if average temperatures
surpassed 120°C for example, there would be no
life on Earth.
Therefore our
little green creatures who might work up a slight
sweat when the temperature soars to 238°C, who
breathe helium instead of oxygen, and who drink
sulfuric acid instead of water are not going to
exist anywhere because carbon-based life-forms
cannot survive under such conditions and carbon-based
life-forms are the only kind there is. Life can
only exist in an environment within limits and
under conditions that are deliberately designed
for life. That is true of life in general and
of human beings in particular.
Earth is such
a deliberately-designed environment.
