Instinctively, when we witness certain happenings we ask ourselves what caused them. While you are reading these sentences, you have no doubt that they are written by someone. This instinct is called the law of cause and effect. How can we not but ask the same question in regard to the total sum of beings and phenomena which we discover in the world? It was by the law of cause and effect that Newton could establish his theory of universal gravity, just from the falling of an apple. The same law is also applied exactly to the huge galaxies. In fact, the law of cause and effect is the basis of all experimental sciences.
The existence of the world of matter can be related to one of the following premises:
- The world exists without having any cause.
- The world exists for it is the cause for itself.
- The world exists because of its effect.
- The world exists because of indefinite causes.
- The world exists because it is related to an Eternal Being.
The law of order invalidates the first assumption.
The second assumption is also invalid, because in order for something to be the reason for itself, it has to precede itself, which in other words means ‘to be and not to be’.
The third assumption is even more ridiculous than the second one.
The fourth is also invalid because it is impossible to traverse an infinite series of causes and effects, as it is impossible to count down from infinity to zero, starting from ‘infinity minus zero’. Also, modern science has told us about the beginning of the universe. Today the limits and the parameters of the universe are measured. Scientists tell us the definite and consistent age of the universe to be 16+/- 3 billion years. Thus, if there is a past, the universe cannot be infinite. Moreover, modern science has confirmed the fact mentioned in the Quran (51:47) that the universe is expanding. The expanding universe cannot be infinite. Therefore, the last assumption is the only valid one, i.e. the world exists because it is related to an Eternal Being: God.
