The brain’s flawless system is, by itself, sufficient for us to realize His sublimity. As we stated above, it contains more than 100 billion nerve cells.1 In order for us to perceive, see, and feel our surroundings, communication has to be established among these 100 billion nerve cells. This is done by somehow making a total of 100 trillion connections.
The means by which this astonishing level of communication is established are exceedingly effective. A special fluid located between the nerve cells contains certain highly specialized chemical enzymes that make electron transport possible. When the electrical signal reaches a nerve ending, electrons are loaded onto these enzymes and then transmitted to other nerves by floating through the fluid between the nerves. The electrical current thus continues to flow by passing on to the next cell. This process takes place in microseconds and with no interruption in the electrical current.
If one of these enzymes fails to perform its function, the transmitted message cannot reach the brain. In other words, although you were looking at your hand, its image would fail to reach your brain.
Moreover, if the enzymes stopped functioning for any reason, the brain’s 100 billion nerve cells would also cease functioning. If these enzymes decided to distribute the massage randomly rather than taking it where it needs to go, the resulting chaos would overturn the entire sensory system and paralyze contact with the outside world.
According to the evolutionists’ logic, which regards everything as purely coincidental, such constant chaos should be unavoidable because conscious entities do not direct this special system. If, as they maintain, everything happens randomly, then countless consecutive chaotic events should occur during any random communication taking place in the cells. However, apart from the most exceptional circumstances, no such mental chaos ever arises and the whole system functions without error. These completely undermine the evolutionists’ logic. Enzymes are always on duty and do not make mistakes. Such a matchless task carried out by unconscious entities made up of proteins can only be inspired by Allah.
Every nerve in the brain and every enzyme, protein, and electron is the work of Allah. The example described here is just one of the countless details created by the One Who controls all entities at every moment and enfolds them with His mercy at all times:
It is Allah Who created the heavens with no support–you can see them–and cast firmly embedded mountains on Earth so that it would not move under you, and scattered about in it creatures of every kind. And We send down water from the sky and make every generous species grow in it. This is Allah’s creation. Show me, then, what those besides Him have created! The wrongdoers are clearly misguided. (Surah Luqman, 10-11
