It is a Scientific Fact That We Only Confront a Copy of the World in Our Brains

We acknowledge that all the individual features of the world are experienced through our sense organs. The information that reaches us through those organs is converted into electrical signals, and the individual parts of our brain analyze and process these signals. After this interpreting process takes place inside our brain, we will, for example, see a book, taste a strawberry, smell a flower, feel the texture of a silk fabric or hear leaves shaking in the wind.
We have been taught that we are touching the cloth outside of our body, reading a book that is 30 cm (1 ft) away from us, smelling the trees that are far away from us, or hearing the shaking of the leaves that are far above us. However, this is all in our imagination. All of these things are happening within our brains.
At this point we encounter another surprising fact; that there are, in fact, no colors, voices or visions within our brain. All that can be found in our brains are electrical signals. This is not a philosophical speculation. This is simply a scientific description of the functions of our perceptions. In her book Mapping The Mind, Rita Carter explains the way we perceive the world as follows:

Each one [of the sense organs] is intricately adapted to deal with its own type of stimulus: molecules, waves or vibrations. But the answer does not lie here, because despite their wonderful variety, each organ does essentially the same job: it translates its particular type of stimulus into electrical pulses. A pulse is a pulse is a pulse. It is not the colour red, or the first notes of Beethoven's Fifth-it is a bit of electrical energy. Indeed, rather than discriminating one type of sensory input from another, the sense organs actually make them more alike.

All sensory stimuli, then enter the brain in more or less undifferentiated form as a stream of electrical pulses created by neurons firing, domino-fashion, along a certain route. This is all that happens. There is no reverse transformer that at some stage turns this electrical activity back into light waves or molecules. What makes one stream into vision and another into smell depends, rather, on which neurons are stimulated.1

We live our entire life within our brain. The people that we see, the flowers we smell, the music we listen to, the fruits we taste, the warmness we feel on our hand… We know all of these in the form they appear in our brains. In reality, neither colors, nor sounds, nor images exist in our brain. The only things that exist in the brain are electric signals. This means that we live in a world formed by the electric signals in our brain. This is not an opinion or a hypothesis, but the scientific explanation of how we perceive the world.

In other words, all of our feelings and perceptions about the world (smells, visions, tastes etc.) are comprised of the same material, that is, electrical signals. Moreover, our brain is what makes these signals meaningful for us, and interprets these signals as senses of smell, taste, vision, sound or touch. It is a stunning fact that the brain, which is made of wet meat, can know which electrical signal should be interpreted as smell and which one as vision, and can convert the same material into different senses and feelings.
Let us now consider our sense organs, and how each one perceives the world.

IT'S NOT OUR EYES THAT SEE, IT IS OUR BRAIN

Because of the indoctrination that we receive throughout our lives, we imagine that we see the whole world with our eyes. Eventually, we usually conclude that our eyes are the windows that open up to the world. However, science shows us that we do not see through our eyes. The millions of nerve cells inside the eyes are responsible for sending a message to the brain, as if down a cable, in order to make "seeing" happen. If we analyze the information we learned in high school, it becomes easier for us to understand the reality of vision.
The light reflecting off an object passes through the lens of the eye and causes an upside-down image on the retina at the back of the eyeball. After some chemical operations carried out by retinal rods and cones, this vision becomes an electrical impulse. This impulse is then sent through connections in the nervous system to the back of the brain. The brain converts this flow into a meaningful, three-dimensional vision.
For example, when you watch children playing in a park, you are not seeing the children and the park with your eyes, because the image of this view forms not before your eyes, but at the back of your brain.
Even though we have given a simple explanation, in reality the physiology of vision is an extraordinary operation. Without fail, light is converted into electrical signals, and, subsequently, these electrical signals reveal a colorful, shining, three-dimensional world. R. L. Gregory, in his book Eye and Brain: The Psychology of Seeing, acknowledges this significant fact, and explains this incredible structure:

We are given tiny distorted upside-down images in the eyes, and we see separate solid objects in surrounding space. From the patterns of simulation on the retinas we perceive the world of objects, and this is nothing short of a miracle.2

A person watching a small child playing with a ball is actually not seeing him with his or her eyes. Eyes are only responsible for delivering light to the back of the eyes. When light reaches the retina, an upside-down and two-dimensional view of the child is formed on the retina. Subsequently this view of the child is converted into an electric current, which is then transmitted to the visual center at the back of the brain, where the child's figure is seen perfectly in three dimensions. Who then sees the child's figure in three dimensions with perfect clarity at the back of the brain? Clearly, the entity we are dealing with is the Soul, which is a being beyond the brain.

All of these facts lead to the same conclusion. Throughout our lives, we always assume that the world exists outside of us. However, the world is within us. Although we believe that the world lies outside us, it is in the smallest part of our brain. For example, the CEO of a company might consider that he has direct contact with the external existence of the company building, his car in the parking lot, his house by the beach, his yacht, and all the people who work for him, his lawyers, his family, and his friends. However, he merely confronts images of all of these things formed in his skull, in a tiny part of his brain. He never knows the actual of the matter in the outside world.
He is unaware of this fact and, even if he knew, would not bother to think about it. If he stood proudly next to his latest-model luxury car, and the wind blew a piece of dust or a small object into his eye, he might gently scratch his itching, open eye and notice that the "material things" he saw moved upside down or to the sides. He might then realize that material things seen in the environment are not stable.

ALL THE THINGS WE SEE AND OWN ARE ACTUALLY IMAGES THAT HAVE BEEN FORMED IN OUR BRAINS When a person rubs his eye, he sees the image of his car moving up and down. This is proof that the observer is seeing not the actual car itself, but its image in his brain.

What this demonstrates is that every person throughout his or her life witnesses everything inside their brain and cannot reach the specific material objects that supposedly cause their experiences. The images we see are copies in our brains of the objects that exist outside of us. We can never know the originals of these copies.
Although German psychiatry professor Hoimar Von Ditfurth is a materialist, he acknowledges this fact about scientific reality:

No matter how we put the argument, the result doesn't change. What stands before us in full shape and what our eyes view is not the "world". It is only its image, a resemblance, a projection whose association with the original is open to discussion.3

For example, when you take a look at the room in which you are sitting, what you see is not the room outside of you, but a copy of the room that exists in your brain. You will never be able to see the original room with your sense organs.

HOW CAN A BRIGHT AND COLORFUL IMAGE APPEAR IN YOUR DARK BRAIN?

There is another point that should not be neglected; light cannot pass through the skull. The physical area in which the brain is located is completely dark, and light cannot possibly penetrate it. However, incredible as it may seem, it is possible to observe a bright and colorful world in this total darkness. Colorful natural beauty, bright sights, all the tones of the color green, the colors of fruits, the designs of flowers, the brightness of the sun, people walking on a busy road, fast cars in traffic, clothes in a shopping mall-are all created in the dark brain.

ALTHOUGH PEOPLE PRESUME THAT THEY SEE THE ORIGINAL OF MATTER LIGHT, SOUND AND COLORS DO NOT EXIST OUTSIDE OF OUR BRAINS; ONLY ENERGY EXISTS  Although the fact that everything we experience is a totality of perceptions formed inside our brains has been scientifically proven, some people still claim that they see the originals of these images that exist outside our brains. However, they will never be able to prove this claim. As mentioned before, light, sound or colors do not exist outside of our brains. Light only exists outside in the form of energy waves and packets of energy, and we only become aware of light when it hits the retina. Similarly, there is no sound. There are only energy waves. Sound only forms when these energy waves reach our ears and are subsequently transmitted to our brains. There is no color outside, either. When we say "there is no color" people might think of a view of black, white or gray. In fact, these are also colors. In the world outside of our brains even the colors of black, white and gray do not exist. Only energy waves in varying strength and frequency exist, and these energy waves are only converted into colors through the cells in the eye and the brain. Quantum physics is another branch of science which shows that the claims of those who say that they see the original of matter are unjustified. The most important truth discovered by quantum physics, which leaves materialists speechless, is that matter is 99.9999999% empty. In his studies of physics and psychology, Peter Russell often makes comments about human consciousness. In an essay adapted from his book, From Science To God, Russell explains this truth thusly: Take, for example, our ideas as to the nature of matter. For two thousand years it was believed that atoms were tiny balls of solid matter-a model clearly drawn from everyday experience. Then, as physicists discovered that atoms were composed of more elementary, subatomic, particles (electrons, protons, neutrons, and suchlike), the model shifted to one of a central nucleus surrounded by orbiting electrons-again a model based on experience. An atom may be small, a mere billionth of an inch across, but these subatomic particles are a hundred-thousand times smaller still. Imagine the nucleus of an atom magnified to the size of a grain of rice. The whole atom would then be the size of a football stadium, and the electrons would be other grains of rice flying round the stands. As the early twentieth-century British physicist Sir Arthur Eddington put it, "matter is mostly ghostly empty space"-99.9999999 percent empty space, to be a little more precise. With the advent of quantum theory, it was found that even these minute subatomic particles were themselves far from solid. In fact, they are not much like matter at all-at least nothing like matter as we know it. They can't be pinned down and measured precisely. They are more like fuzzy clouds of potential existence, with no definite location. Much of the time they seem more like waves than particles. (Peter Russell, The Mystery of Consciousness and the Meaning of Light, 12 Oct 2000,  http://www.arlingtoninstitute.org/futureedition/From_Science-To-God.htm) We can thus see that science shows us that beyond the confines of our brain, there are only energy waves and energy packets. Beyond our brain there is no light, no sound and no color. Additionally, atoms and subatomic particles that form a material are actually loose groups of energy. As a result, material is comprised of space.  In reality, God creates matter through a vision with these qualities.

Imagine a barbecue burning in front of you. You can sit and watch the fire for a long time, but throughout this entire time, your brain never deals with the original of light, brightness or heat from the fire. Even when you feel its heat and see its light, the inside of your brain remains dark and maintains a constant temperature. It is a profound mystery that, in the darkness, the electrical signals turn into colorful, bright visions. Anyone who thinks deeply will be amazed by this wondrous occurrence.

EXTREMELY REALISTIC "COPY IMAGES" THAT FORM IN THE BRAIN As also seen in this comparison, despite their dozens of years of efforts, people have not been able to provide vision which has the same sharpness and high quality as the vision of an eye. However, your eye, which is only composed of protein, lipid and water, creates what they have not succeeded by forming a very realistic image. This is such a perfect sharpness that everyone thinks that the image he or she sees is the original. They cannot realize that everything they see actually forms in the brain. Even though they do not see the original, they are convinced that they watch the real picture, because the quality of the picture that forms in the brain is perfect. The one who sees the picture is not the proteins, molecules or atoms in the brain, but the soul which God breathed from His Spirit to man.

LIGHT IS ALSO COMPOSED IN OUR BRAIN

While discussing what science has discovered about vision, we mentioned that the light we receive from the outside gives rise to some movements of the eye cells, and these movements form a pattern from which our visual experience emerges. However, there is another point that we need to make: Light, as we perceive it, does not reside outside of our brain. The light we know and understand is also formed within our brain. What we call light in the outside world, which is supposedly outside our brains, consists of electromagnetic waves and particles of energy called photons. When these electromagnetic waves or photons reach the retina, light, as we experience it, begins to come into existence. This is the way light is described in physical terms:

The term "light" is used for electromagnetic waves and photons. The same term is used in physiology, as the feeling experienced by a person when electromagnetic waves and photons strike the retina of the eye. In both objective and subjective terms, "light" is a form of energy coming into existence in the eye of a person, which a person becomes aware of through the retina by the effects of vision.4

Consequently, light comes into existence as a result of the effects that some electromagnetic waves and particles cause in us. In other words, there is no light outside our bodies which creates the light we see in our brains. There is only energy. And when this energy reaches us we see a colorful, bright, and light-filled world.

COLORS ALSO ORIGINATE IN OUR BRAINS

Starting from the time, we are born, we deal with a colorful environment and see a colorful world. However, there isn't one single color in the universe. Colors are formed in our brains. Outside there are only electromagnetic waves with different amplitudes and frequencies. What reaches our brains is the energy from those waves. We call this "light", although this is not the light we know as bright and shiny. It is merely energy. When our brains interpret this energy by measuring the different frequencies of waves, we see "colors". In reality, the sea is not blue, the grass is not green, the soil is not brown and fruits are not colorful. They appear as they do because of the way we perceive them in our brains. Daniel C. Dennett, who is known for his books about the brain and consciousness, summarizes this universally accepted fact:
The common wisdom is that modern science has removed the color from the physical world, replacing it with colorless electromagnetic radiation of various wavelengths.5

There are no colors in the world outside. Colors are only formed in the eyes and brain of the observer. Only energy packets of various wavelengths exist in the external world. It is our brains that transform this energy into colors.

In The Amazing Brain, R. Ornstein and R. F. Thompson have stated the way colors are formed as follows.

'Color' as such does not exist in the world; it exists only in the eye and brain of the beholder. Objects reflect many different wavelengths of light, but these light waves themselves have no color.6

There is no light and no color outside of our brains. Colors and light are formed in our brains. In the retina in the eye, there exist three groups of cone cells, each of which react to different wavelengths of light. The first of these groups is sensitive to red light, the second is sensitive to blue light and the third is sensitive to green light. Different levels of stimulus to each of the three sets of cone cells gives rise to our ability to see a world full of color in millions of different tones.

In order to understand why this is so, we must analyze how we see colors. The light from the sun reaches an object, and every object reflects the light in waves of different frequencies. This light of varying frequency reaches the eye. (Remember that the term "light" used here actually refers to the electromagnetic waves and photons, not the light which is formed in our brains.) The perception of color starts in the cone cells of the retina. In the retina, there are three groups of cone cells, each of which reacts to different frequencies of light. The first group is sensitive to red light, the second is sensitive to blue light, and the third is sensitive to green light. With the different levels of stimulations of these cone cells, millions of different colors are formed. However, the light reaching the cone cells cannot form colors by itself. As Jeremy Nathans of John Hopkins Medical University explains, the cells in the eye do not form the colors:

All that a single cone can do is capture light and tell you something about its intensity. It tells you nothing about color.7

The cone cells translate the information they get about colors to electrical signals thanks to their pigments. The nerve cells connected with these cells transmit these electrical signals to a special area in the brain. The place where we see a world full of color throughout our lives is this special area in the brain.
This demonstrates that there are no colors or light beyond our brains. There is only energy which moves in the form of electromagnetic waves and particles. Both color and light exist in our brains. We do not actually see a red rose as red simply because it is red. Our brain's interpretation of the energy that reaches our eye leads us to perceive that the rose is red.

In the picture shown left, the green area on the left hand side appears to be dark while the green area on the right hand side appears lighter. In fact, the tones of both greens, as shown in the bottom are exactly the same. The red and orange colors next to the green bands trick us into thinking that the two green colors are of different tones. This again points to the fact that we do not see the original material world, we only see our interpretation of it in our brain.

Color blindness is proof that colors are formed in our brains. A small injury in the retina can lead to color blindness. A person affected by color blindness is unable to differentiate between red and green colors. Whether an external object has colors or not is of no importance, because the reason why we see objects colorful is not their being colorful. This leads us to the conclusion that all of the qualities that we believe belong to the object are not in the outside world, but in our brains. However, since we will never be able to go beyond our perceptions and reach the outside world, we will never be able to know the originals of materials and colors. The famous philosopher, Berkeley, acknowledges this fact with the following words:

If the same things can be red and hot for some and the contrary for others, this means that we are under the influence of misconceptions.8

ALL SOUNDS ARE FORMED IN OUR BRAINS THERE ARE NO SOUNDS IN THE OUTSIDE WORLD
