HARUN YAHYA

Another experiment is trying to thread a needle with one eye closed.
You will find this impossible, because with monocular vision, you have no
sense of depth.
Sometimes, certain objects appear "doubled" to our vision. This hap-
pens when we focus in on one specific point—near or far—and consequently
pay less attention to its surroundings. Hold a pencil in the air close to your
face. Then with your other hand, take another pencil and hold it behind the
first, at arm's length. When you focus on the more distant pencil, the closer
one will appear doubled. If you focus on the closer one, the distant pencil
will similarly appear doubled. Without this ability to focus, you would al-
ways be seeing double, no matter what you focused on.
Merging two separate images and creating a three-dimensional result is
a process that requires perfect calculations. If the eyes had developed coinci-
dentally, what are the odds that such fine synchronization could be
achieved? What coincidences would achieve a system that can analyze and
combine millions of bits of information every second? If the eyes did not
work in harmony, the brain would receive confused signals and create a jum-
bled image for us to perceive. But since this is not the case, it's not possible to
reason this system was developed through a series of coincidences. The flaw-
lessness of God's creations is described in a verse as follows:
He Who created the seven heavens in layers. You will not find any
flaw in the creation of the All-Merciful. Look again—do you see any
gaps? (Qur'an, 67: 3)

How Distance Is Determined
In order to determine how far away something is, the brain considers
how large it appears in the image on the retina. As long as that object's actual
size is known, the brain makes a rough calculation—based on the perceived
size of the image—of how far away that object really is.
One extraordinary aspect of this process is that it takes place completely
below the conscious level. You don't notice it, but you are actively determin-
ing whether every object in view is nearby or far away. If this process never
took place, you would be unable to drive or even walk. Without perspective,
