The Cosmological Argument attempts to prove that God exists by showing that there cannot be an infinite number of regressions of causes to things that exist. It states that there must be a final uncaused-cause of all things. This uncaused-cause is asserted to be God.
The Cosmological Argument takes several forms but is basically represented below.
- Things exist.
- It is possible for those things to not exist.
- Whatever has the possibility of non existence, yet exists, has been caused to exist.
- Something cannot bring itself into existence, since it must exist to bring itself into existence, which is illogical.
- There cannot be an infinite number of causes to bring something into existence.
- An infinite regression of causes ultimately has no initial cause, which means there is no cause of existence.
- Since the universe exists, it must have a cause.
- Therefore, there must be an uncaused cause of all things.
- The uncaused cause must be God.
Strengths of the argumentThe strengths of the Cosmological Argument lie in both its simplicity and easily comprehensible concept that there cannot be an infinite number of causes to an event. Some arguments for God's existence require more thought and training in terms and concepts, but this argument is basic and simple. Also, it is perfectly logical to assert that objects do not bring themselves into existence and must, therefore, have causes.
Weaknesses of the argumentOne of the weaknesses of the argument is that if all things need a cause to exist, then God Himself must also, by definition, need a cause to exist. But this only pushes causation back and implies that there must be an infinite number of causes, which cannot be.
Also, by definition, God is uncaused.
Me - God is supernatural and not material and therefore that is why He is not bound by material laws and time. He invented both. The only logical cause exists outside of the existence that includes our concept of a cause.
The argument to be made here is a form of the cosmological argument which originated in the philosophy of Plato and Aristotle, and was refined by Thomas Aquinas. With the advances of modern science, the version I will provide will be perhaps clearer for some than the form set forth by Aquinas. It is a composite of Aquinas’ vertical cosmological argument and the Kalam cosmological argument:
- Everything that has a beginning needs a cause.
- The universe had a beginning.
- The universe needs a cause.
- There cannot be an infinite regress of caused causes.
- There must be a cause for all else which has no beginning and needs no cause for its own existence.
There are several pieces of evidence that support the contention of Premise #2 that the universe had a beginning. The scientific community has long since accepted the beginning of the universe via the big bang. To quote from Norman Geisler, “Logically and mathematically, the evidence for the big bang suggests that originally there was no space, no time, and no matter.” (Geisler, 1999) Here are some much summarized points to demonstrate why the universe is thought to have begun, most of which was set forth by astronomer Robert Jastrow (Jastrow, 1982), and some of which has been subsequently discovered:
- The second law of thermodynamics shows that usable energy is running down, which means there had to be a time when the process started. If not (if there was infinite time before us), all the energy in the universe would have been used up, and we would not be here.
- The universe is expanding. Traced backward, there would have to be a place it started to expand. The universe cannot be continually expanding and retracting, since it would eventually run out of energy and collapse on itself.
- If the universe were eternal, time would also be eternal. But we could never have gotten to this point if time were infinite. Time measures the intervals between movements. There was no movement until the universe began, therefore there was no time. It would be impossible to traverse an infinite amount of time.
- We see matter continually degrading rather than becoming more complex. If things fall apart when left to themselves, the world could not be infinite. It would already be destroyed. Only that which is self-sufficient and self-sustaining can be infinite.
- There is a radiation “echo” throughout the universe which scientists at first thought was merely static or a malfunction of their equipment. This emanation of radiation is consistent with what would be expected of an enormous explosion in the past, down to the wavelength that should be produces by such light and heat.
- After the big bang theory became the predominant view of the universe’s origin, scientists began looking for a large mass of matter associated with the original explosion, but none could be found until the Hubble made it possible to find it. One astronomer, Michael Lemonick said “by peering back into the beginning of time, a satellite finds the oldest structure ever observed—evidence of how the universe took shape 15 billion years ago.” (Lemonick, 1993) This was exactly what they were looking for, if the theory were to be shown to be true beyond a reasonable doubt.
Premise #4: One cannot posit an unending string of caused causes. This just seems obvious, but if you need some reasons why this is so, I will try, though it seems the more obvious something is, the more difficult it is to explain. If the causes of the universe itself needed a cause, and the cause of that cause needed a cause, ad infinitum, the string of causes could never be put into motion. An infinite series is impossible because one more moment (or cause) could always be added. But it is impossible to add to an infinite. Plus, if there were an infinite number of causes, there would be an infinite number of moments in which the act of causation took place. But if there were infinite moments, the current moment could have never arrived, since it is impossible to traverse an infinite number of moments. Quantitative infinity is merely a convention of mathematics, but has no metaphysical counterpart. Without a first cause, there is no causality in the series.
Conlusion (#5): If the universe needs a cause for its existence, and there cannot be an unending string of contingent causes, there must be a Cause whose existence is necessary. (“Necessary” is used in opposition to “contingent,” in which a contingent being needs a cause for its existence, and a necessary Being has no cause, and no beginning.) Something must be eternal for anything else to exist. For nothing produces nothing. If nothing ever existed, then nothing could exist. But the universe, as you have seen, is not eternal; it began to exist. So, there must be something else, or someone else, who does not depend upon any other for existence, but exists by virtue of itself. This is beyond human understanding (because we have never experienced anything that is beginning-less), but it is not contradictory to logic for there to be a being without a beginning. As I hope to have shown, no other state of affairs is possible, for if something is not eternal, than nothing could have ever existed at all.
This has been a brief account of the cosmological argument. It has not taken into consideration certain objections. These objections are dealt with well in Norman Geisler’s Baker Encyclopedia of Christian Apologetics in the article “Cosmological Argument.” This argument does not, in itself, produce the Christian God, but leads to it if one follows all of the implications and other evidence for the God of the Bible, which cannot be provided in one article. This argument is merely an attempt to show that there is a Supreme Being to which the universe owes its existence.

The Teleological Argument is also known as the "argument from design." Quite simply, it states that a designer must exist since the universe and living things exhibit marks of design in their order, consistency, unity, and pattern.
A typical analogy of this is the Watchmaker Argument, which was given by William Paley (1743-1805). The argument goes as follows. If you found a watch in an empty field, you would logically conclude that it was designed and not the product of random formation. Likewise, when we look at life and the universe, it is natural to conclude there is a designer since we see how perfectly the universe and life forms operate. The eye is typically used as an example of design. It is a marvelous development. In order for it to work, there must be many different convergent parts that individually have no function but have value only in a designed whole. It is only in the combined total that they exhibit their total function. This function is by design.
Paley's argument is as follows:
- Human artifacts are products of intelligent design.
- The universe resembles human artifacts.
- Therefore the universe is a product of intelligent design.
- But the universe is complex and gigantic, in comparison to human artifacts.
- Therefore, there probably is a powerful and vastly intelligent designer who created the universe.
Strengths of the argumentThis argument is simple to understand and has merit, since humans are designers by nature and it is natural to think in terms of things having purpose. It is also consistent with Rom. 1:20:
I think the teleological argument carries weight because it is consistent with Scripture. The Bible states that we are made in God's image. Therefore, there are certain things with which we will resonate. Even though the unbeliever suppresses the truth of God in his unrighteousness (Rom. 1:18-32), the truth is still there."For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse."
Additionally, evolutionists have difficulty accounting for apparent design in objects like the eye, the heart, and the brain where many different parts come together to form the whole. These individual parts have no purpose except in the function of the whole. How can evolution account for these detailed congruent occurrences? So far, it can't.
Weaknesses of the argumentThe idea that the universe is designed is subjective. Different observations in the natural world can produce different theories to account for their existence. Also, this proof is built upon an analogy. If we find things in the universe that are chaotic, then by analogy, that would imply there is no designer.
