With the onset of puberty, there is a similarity in the developments in the male and female bodies. The female reproductive cell, the egg, along with the female reproductive system is prepared to complement the male reproductive system.
With the coming of puberty in women, just as in men, the hypothalamus knows exactly when the time has come to send commands to the pituitary gland to produce the hormones required to bring the egg cells to maturation. The pituitary gland receives these commands, immediately obeys them and begins to produce the needed hormones.
The production of reproductive cells in women is not continuous as it is in men. This production occurs at particular times. It is the job of the pituitary gland to determine the time. The pituitary gland assures the production of a hormone that will bring the primary egg cells to maturation in the ovary. This hormone knows very well where it will perform its function, and going straight to the ovary, it announces that the time has come for the maturation of the egg. At this, the egg cells immediately understand the command and begin an intense activity inside the ovary, leading to the maturation of the egg.13
Now, let us examine this information more deeply. How does this tiny secretory gland called the hypothalamus determine the time? And how does it calculate the exact timing of this process, which has occurred in millions of women past and present, without getting confused? The hypothalamus is located at the base of the brain; it is not a timing mechanism, it has no relation with the world outside the brain; it is a piece of flesh composed of cells. The function of this piece of flesh in determining time is an extraordinary thing that cannot be ignored. But this is just a tiny detail of the wondrous occurrences that happen continuously in the human body. This kind of astounding process continues endlessly, at every moment and in every square millimetre of the human body. For example, an amazing miracle happens in the pituitary gland: a command sent by the hypothalamus is read and understood; on the basis of this understanding a decision is made; according to this decision, substances are produced and sent with other productive material without error to a distant and hitherto unseen area. The pituitary gland is also a collection of cells. The coming together of these cells and their conscious understanding of the commands sent to them and their carrying out a command they have understood is an extraordinary thing. What consciousness makes it possible for this collection of cells to "understand", "conceive", "draw conclusions", "arrive at decisions" and "put the decision into effect"?
The human body is a dark environment into which light does not penetrate and where many fluids move at great speed through the vessels; it is a dense and complicated place. No evolutionist has ever been able to explain how a mass of molecules in this dense environment can go where it wants in the complex mass by crossing over other materials many times its own size and without suffering harm or loss, or how they can even use some means to send some other substances to the places where they are needed. This is because evolutionists' sole refuge, when they come face to face with these marvellous proofs of creation, is chance; but there is no room for chance in the complex structure of the human body or of any other living thing. At this point, we must recall that, in the course of all these events, the intelligence and conscience we encounter do not belong to any cell. What we call a cell has no eyes to see with, to tongue to speak or be understood with, and no ears to hear with. Cells are the creation of God; they are only the means of carrying out His commands; and at every moment, by His inspiration, they effect processes too wondrous ever to have come from themselves.
