The Argument Against Any Cosmological Argument

I’m convinced that the cosmological argument is the most convincing argument for God among the least skeptical people. This is speculation on my part, but it is informed speculation. Let’s look at the argument.
  1. Everything that exists has a cause of its existence.
  2. The universe exists.
    Therefore:
  3. The universe has a cause of its existence.
  4. If the universe has a cause of its existence, then that cause is God.
    Therefore:
  5. God exists.
This form of the argument is laughable. The conclusion of (5) makes God subject to (1) which begs the question who or what created God? It doesn’t answer the question of First Cause thereby making it pointless. Many theists realize this and have tweaked the argument to avoid criticism...or tried to.

Kalam cosmological argument
  1. Whatever begins to exist has a cause.
  2. The universe began to exist.
  3. Therefore, the universe has a cause.
This argument takes into account the Big Bang Theory, giving weight to premise (2). (I must say that it bothers me that many theists only find the science that could support their beliefs compelling while finding the rest somehow erroneous) I could argue that (1) is an assumption, but based on experience, it seems correct. William Lane Craig throws in his two cents with a sub argument.

Argument based on the impossibility of an actual infinite:
  1. An actual infinite cannot exist.
  2. An infinite temporal regress of events is an actual infinite.
  3. Therefore, an infinite temporal regress of events cannot exist.
I imagine WLC is attempting to make the argument stronger in regards to God as First Cause, but claiming that an infinite can not exist makes God, who relies on infinities in a variety of ways, nonexistent. If God cannot exist infinitely into the past, he is not eternal and subject to the necessity of a cause according to this vary argument.

Then we have...
Thomistic cosmological argument
  1. What we observe in this universe is contingent (i.e. dependent, or conditional)
  2. A sequence of causally related contingent things cannot be infinite
  3. The sequence of causally dependent contingent things must be finite
And...
Leibnizian cosmological argument
  1. Every existing thing has an explanation of its existence, either in the necessity of its own nature or in an external cause.
  2. If the universe has an explanation of its existence, that explanation is God
  3. The universe is an existing thing.
  4. Therefore the explanation of the universe is God.
Which can be tied together to be...
  1. Every finite and contingent being has a cause.
  2. A causal loop cannot exist.
  3. A causal chain cannot be of infinite length.
  4. Therefore, a First Cause (or something that is not an effect) must exist.
If your cosmological argument of choice isn’t here, I’m not surprised. The apologist presents whichever form has help up the best under criticism, which speaks more to the quality of religious debates in their past than the quality of the argument. Ultimately they all rest on the same assumptions–that the universe needs a cause and that the cause must be God. If you define God as simply the thing that causes the universe, then I freely admit that God could exist, but most define God as an agent possessing will/intellect/personality/and the like, which is a definition unwarranted by every cosmological argument.

The arguments also suffer from a fundamental misunderstanding of the universe. The Big Bang Theory, which lends weight to the claim that the universe even had a beginning, involves space and time’s origin as well. Ask a layperson to describe the Big Bang and you’ll likely hear about an explosion in space from which all matter and energy came forth to eventually form stars, planets, etc. I would guess this misconception draws the ignorant to the First Cause arguments. The scientific consensus is that space/time exploded outward with the matter and energy that eventually formed the universe. Scientists determined this, in part, from observations of celestial bodies drifting apart, marking the predicted expansion of space. The repercussions of this accurate understanding of the Big Bang Theory means that time began at the moment of the effect (the Big Bang) leaving no time for the cause. This leaves the apologist with the task of weighing which counter-intuitive statement is more logical--that every effect must be preceded by a cause or that anything can precede the arrow of time. It’s quite the chronological conundrum...that somehow doesn’t bother theists that much.

I’m not sure “logical” is the operable word here. At the first moment of the Big Bang, and therefore time, everything that would become the universe was a singularity, or something close to it. At this size it was subject to the strangeness that is quantum mechanics. While scientists don’t yet have clear explanations for everything we observe at the quantum level, we have repeated and repeatable results that inform particle/wave duality, the uncertainty principle, super positioning and all kinds of other phenomenon that most everyone would say seems impossible if they don't see it with their own eyes and instruments. Some of these phenomenon even open possibilities that may violate causality and the arrow of time. I look forward to having my mind further blown as humanity hashes this all out.

First Cause

I consider the Cosmological Argument the best argument for a creator God. Given the theme of this blog, I don’t consider it a particularly good argument, but it is the best none the less. What follows is the most fair, if not conclusive, rebuttal I have to give.

The argument from the origin of the universe, or the Cosmological Argument dates back to the beginning of apologetics. If you are interested in the history, Google it. I plan on skipping ahead to the modern version of the argument sometimes called the Kalam cosmological argument.

  1. Whatever begins to exist has a cause.
  2. The Universe began to exist.
  3. Therefore, the Universe had a cause.

This form of the argument is meant to avoid the easy dismissal of “if everything that exists needs to have a cause, then what caused God?” and the fallacies associated with it. It is implied that God did not begin to exist while the universe did.

It is one of those rare cases that a scientific discovery seemingly hurt the atheistic position. It is hard to argue that the universe did not begin to exist after the Big Bang Theory. Luckily, there are still multiple avenues of rebuttal.

  • There is no evidence that there is a God, eternal or otherwise, other than the universe’s existence. (If you consider the other arguments that apologists pose as further evidence, stay tuned, I will take them on in future posts.) The idea of a willful, intelligent, universally powerful entity is an extraordinary claim--which, according to Carl Sagan who I happen to agree with, requires extraordinary evidence. At best, God is a hypothesis that can’t be tested, makes no predictions, and contributes little to explaining how we came to be.
  • There are other ideas in theoretical physics that could account for the cause of the Big Bang. For example, the theory of Loop Quantum Gravity says that our universe was preceded by an identical, reversed universe that contracted into the singularity that expanded into our universe. There are multiple theories involving the notion of a multiverse, including one where ours is just a bubble universe that emerged from quantum foam. Actually, the word “quantum” comes up a lot, which is a hard concept to sell to someone who believes the much simpler idea of a creator. None of these theories have much hard evidence behind them, but the fact that we have found elementary particles that pop in and out of existence and can possibly travel through time, makes them all stand on a better foundation of reality than a supreme being existing outside of space and time.
  • God would have to exist outside space and time and we have no evidence that there is such a place. The downside of the updated Kalam cosmological argument is the same as it’s advantage--taking into account the Big Bang. The Big Bang did not only explode out matter and energy, but also space and time. It’s not accurate to think of “before the Big Bang” because chronologically “before” didn’t exist. To be an atheist, you only need to accept that the universe either didn’t have a cause, was self-caused, or has a natural cause that we don’t yet understand. To be a theist, you need to accept a variety of magical concepts.
  • To posit God is explaining one mystery with another mystery. To most believer’s the buck stops at God, there is no point in trying to understand anything further, because we can’t know the Mind of God. As a proponent of science, I prefer to increase humanity’s collective knowledge and learn more about reality. It is the drive that got us to the moon, split the atom and, like it or not, is making the world more secular. Stopping with God gets us the dark ages. If you insist in believing God did all this, don’t sit on your laurels, find some way to prove it. If you don’t, science will prove you wrong.
