Breathing, eating, walking, etc, are very natural human functions. But
most people do not think how these basic actions take place. For example,
when you eat a fruit, you do not think how it will be made useful to your
body. The only thing on your mind is eating a healthy meal; at the same
time, your body is involved in extremely detailed processes unimaginable
to you in order to make this meal a health-giving thing.
The digestive system where these detailed processes take place starts
to function as soon as a piece of food is taken into the mouth. Being
involved in the system right at the outset, the saliva wets the food and
helps it to be ground by the teeth and slide down the oesophagus.
The oesophagus helps the food be transported to the stomach where a perfect
balance is at work. Here, the food is digested by the hydrochloric acid
present in the stomach. This acid is so strong that it has the capacity
to dissolve not only the food but also the stomach walls. Of course, such
a flaw is not permitted in this perfect system. A secretion called mucus
which is secreted during digestion covers all the walls of the stomach
and provides a perfect protection against the destructive effect of the
hydrochloric acid. Thus the stomach is prevented from destroying itself.
The point that deserves attention here is that evolution can by no means
explain the system briefly summarised earlier. Evolution maintains that
today's complex organisms have evolved from primitive beings by the gradual
accumulation of small structural changes. However, as stated clearly,
the system in the stomach could in no way have been formed step by step.
The absence of even one factor would bring about the death of the organism.
When food is received into the stomach, the gastric juices acquire the
ability to break down food as a result of a series of chemical changes.
Now, imagine a living being in the so-called evolutionary process in whose
body such a planned chemical transformation is not possible. This living
being, unable to acquire this ability, would not be able to digest the
food it ate and would starve to death with an undigested mass of food
in its stomach.
In addition, during the secretion of this dissolving acid, the stomach
walls simultaneously have to produce the secretion called mucus. Otherwise,
the acid in the stomach would destroy the stomach. Therefore, in order
for life to continue, the stomach must secrete both fluids (acid and mucus)
at the same time. This shows that not a step-by-step coincidental evolution
but a conscious creation with all its systems must, in effect, have been
at work.
What all this shows is that the human body resembles a huge factory made
up of many small machines that work together in perfect harmony. Just
as all factories have a designer, an engineer and a planner, the human
body has an "Exalted Creator".
