Miracles in Our Body
'A HALF-DEVELOPED EYE CANNOT SEE'
What comes to your mind first when you hear the word "eye"? Are you aware that one of the most crucial things in life for you is your ability to see? Even if you are, have you ever thought what other signs your eye bears?
The eye is one of the most manifest pieces of evidence that living creatures are created. All sight organs, including animal eyes and the human eye, are extremely striking examples of perfect design. This exceptional organ is so overwhelmingly complex that it surpasses even the most sophisticated man-made devices in the world.
In order for an eye to see, all of its parts have to co-exist and work in harmony. For instance, if an eye happened to have lost its eyelid, but still had all the other parts such as the cornea, conjunctiva, iris, pupil, eye lenses, retina, choroid, eye muscles, and tear glands, it would still be greatly damaged and soon lose its seeing function. In the same manner, even if all its organelles were present, if the tear production were stopped, the eye would soon dry out and become blind.
"The chain of coincidences" posited by evolutionists loses all its meaning against the complex structure of the eye. It is not possible to explain the existence of the eye other than as a matter of special creation. The eye has a multi-sectioned complex system and, as discussed above, all of these individual sections had to come into existence at the same time. It is impossible for a half-developed eye to function at "half capacity". In such a circumstance, the act of seeing can by no means take place. An evolutionist scientist admits to this truth:
The common trait of the eyes and the wings is that they can only function if they are fully developed. In other words, a halfway-developed eye cannot see; a bird with half-formed wings cannot fly.
In this case, we again face that very important question: who created all of the components of the eye all at once?
The owner of the eyes is obviously not the one who makes the decision about their formation. For it is impossible for a being devoid of the knowledge of what seeing is like, to desire to have a seeing organ and have it attached to his body. So we have to accept the existence of a Possessor of superior Wisdom Who has created living beings with senses such as seeing, hearing, and so on. Another claim is that unconscious cells gained consciousness-requiring functions such as seeing and hearing by their own desire and effort. It is crystal clear that this is impossible. In the Qur'an, it is stated that seeing has been bestowed upon living beings by God:
Say: He it is Who brought you into being and made for you the ears and the eyes and the hearts: little is it that you give thanks. (The Qur'an, 67:23)
HOW DO CELLS RECOGNISE ONE ANOTHER?
In our high school or university years, we all learn about the formation of the human body. So we know that the embryo, which is initially only a piece of flesh, which turns into a body over time. In this process, the cells start to differentiate, some forming arms, others internal organs and yet others eyes. Each cell knows where to go, which organ it will form, how much it will reproduce, and when it will stop. However, the quotation below informs us about a different, awesome aspect of the embryo's development:
If we separate the cells of an embryo belonging to various organs - provided that we decrease the amount of calcium in the environment -, and further mix these different kinds of cells thoroughly in an appropriate environment, then when they come in contact with each other again, these cells KNOW one another and the cells of the same organ form individual groups.
That is to say, if we first separate cells from one another and then unite them again, cells that would form the same organ will recognise one another and re-unite.
How do these cells, bereft of a brain, nervous system, eyes and ears, recognise one another? How can these beings without consciousness and wisdom, which are only collections of molecules, select those cells which share the same qualities from all the various other cells? How do they know that they will later come together and form the same organ? What is the source of this great consciousness displayed by unconscious molecules? The source of this consciousness is God, the Lord of all the Worlds, Who created the whole universe from nothing.
We will show them Our Signs on the horizon and within themselves until it is clear to them that it is the truth. Is it not enough for your Lord that He is a witness of everything? (The Qur'an, 41:53)
THE ARMY INSIDE MAN
Every day, a war is fought in the innermost parts of your body unperceived by you. On the one side are viruses and bacteria that aim to intrude into your body and take it under control and on the other are the immunity cells that protect the body against these enemies.
The enemies wait in an offensive state to make their way into the area they aim at and they head towards the target area at the first opportunity. However, the strong, organised and disciplined soldiers of the target area do not easily give in to the enemies. First, the soldiers who swallow and neutralise the enemy soldiers (phagocytes) arrive at the battleground. However, sometimes the fight is tougher than these soldiers can handle. On such occasions, other soldiers (macrophages) are summoned up. Their involvement causes alarm in the target area and other soldiers (helper T cells) are also called to battle.
These soldiers are very familiar with the local populace. They quickly distinguish their own army from that of the enemy. They immediately activate the soldiers assigned to weapon production (B cells). These soldiers have extraordinary abilities. Although they never see the enemy, they can produce weapons which will render the enemy ineffectual. In addition, they carry the weapons they produce as far as they should be taken. During this journey, they succeed in the difficult task of not causing any harm either to themselves or to their allies. Later, the striker teams cut in (killer T cells). These discharge the poisonous material they carry on themselves at the most vital spot of the enemy. In case of victory, another group of soldiers arrives at the battleground (suppressor T cells) and sends all the warriors back to their camp. The soldiers who arrive at the battleground last (memory cells) record all relevant information about the enemy, so that it can be used in the event of a similar invasion in the future.
The excellent army discussed above is the immune system in the human body. Everything explained above is done by microscopic cells unobservable to the naked eye. (For more information please see The Miracle of the Immune System by Harun Yahya)
How many people are aware that they have such an organised, disciplined and perfect army inside their bodies? How many of them are aware that they are surrounded on all sides by microbes that, if unimpeded, would cause them to catch serious illnesses or even die? Indeed, there are many dangerous microbes in the air we breathe, the water we drink, the food we eat, and the surfaces we touch. While one is unaware of all that is going on, the cells in one's body make strenuous efforts to save one from an illness that may even bring about one's death.
The ability of all immunity cells to distinguish enemy cells from body cells, the ability of B cells to prepare a weapon to neutralise the enemy that they have never seen, their ability to carry these weapons as far as they have to be taken without adversely affecting any body cells, the signal-receiving cells' fulfilling their duty completely without making any objections, each of them knowing what to do, their returning to their places without any problem as soon as they are finished with their work, and the abilities of the memory cells are only some of the distinctive characteristics of this system.
For all these reasons, the story of the formation of the immunity system is never taken up by any evolutionist writer.
It is extremely difficult for a person without an immunity system or with an ill-functioning one to survive, since he would be exposed to all the microbes and viruses in the outside world. Today, such people can exist only in special enclosures with no direct contact with anyone or anything outside. Therefore, it is impossible for a person without an immunity system to survive in a primitive environment. This leads us to the conclusion that an extremely complex system such as the immune system could only have been created all at once and with all of its elements intact.
