Part of the problem lies in the nature of the question itself. If I were to ask you, “What sound does silence make?” you’d start to appreciate the problem. This latter question is nonsensical because silence is “soundless”; silence is, by definition, “the lack of sound”. There’s something equally irrational about the question, “Who created God?” God is, by definition, eternal and uncreated. It is, therefore, illogical to ask, “Who created the uncreated Being we call God?” And, if you really think about it, the existence of an uncreated “first cause” is not altogether unreasonable:
It’s Reasonable to Believe The Universe Was Caused
Famed astronomer Carl Sagan once said, “The Cosmos is everything that ever was, is and will be.” If this is true, we are living in an infinitely old, uncaused universe that requires no first cause to explain its existence. But there are good scientific and philosophical reasons to believe the universe did, in fact, begin to exist. The Second Law of Thermodynamics, the expansion of the universe, the Radiation Echo, and the problem of Infinite Regress cumulatively point to a universe with a beginning. In the classic formulation of the Kalam cosmological argument: (1) whatever begins to exist has a cause, (2) the universe began to exist, therefore, (3) it is reasonable to believe the universe has a cause.
It’s Reasonable to Accept the Existence of An Uncaused “First Cause”
This “first cause” of the universe accounts for the beginning of all space, time and matter. It must, therefore, be non-spatial, a temporal and immaterial. Even more importantly, the first cause must be uncaused. If this was not true, the cause of the universe would not be the “first” cause at all. Theists and atheists alike are looking for the uncaused, first cause of the cosmos in order to avoid the irrational problem of an infinite regress of past causes and effects. It is, therefore, reasonable to accept the existence of an uncaused, first cause.
It’s Reasonable to Believe God Is the Uncaused, “First Cause”
Rationality dictates the ultimate cause of the universe, (even if it isn’t God), must have certain characteristics. In addition to being non-spatial, a temporal, immaterial and eternal (uncaused), it must also be powerful enough to bring everything into existence from nothing. Finally, there is good reason to believe the cause of the universe is personal. Impersonal forces cannot cause (or refuse to cause) at will. The minute an impersonal force exists, its effect is experienced. When the impersonal force of gravity is introduced into an environment, for example, its effect (the gravitational attraction) is felt immediately. If the cause of the universe is simply an impersonal force, its effect (the beginning of the universe) would occur simultaneous with its existence. In other words, the cause of the universe would only be as old as the universe itself. Yet we accept the reasonable existence of an uncaused first cause (one that is not finite like the universe it caused). For this reason, a personal force, capable of willing the beginning of the universe, is the best explanation for the first cause of the cosmos. This cause can be reasonably described as non-spatial, a temporal, immaterial, eternal, all-powerful and personal: descriptive characteristics commonly reserved for the Being we identify as God.
All of us, whether we are atheists or theists, are trying to identify the first cause of the universe. The eternal nature of this non-spatial, a temporal, immaterial cause is required in order to avoid the problem of infinite regress. It is, therefore, irrational to ask “What caused the uncaused first cause?” It is far more reasonable to simply recognize the attributes of this cause as an accurate description of God.
