In answer to the question why does the Universe exist, many traditional cultural answers have been simply to state that God did it1. The belief that "everything must have a cause, therefore God exists" is called a First Cause argument. But that merely results in new questions: (1) why did god create the Universe? and (2) why does God exist? If it is valid to say "everything has a cause except God", it is more likely that everything has a cause except the Universe. If God doesn't need a cause because it is infinite, it is more likely that the natural Universe has existed forever and therefore doesn't need a cause. You therefore make fewer assumptions, and cause fewer puzzles, if you admit that you believe in one uncaused entity, and that that one uncaused entity is the Universe itself.
Aside from causal arguments, there are problems with the nature of god. If God can make plans and think logically, then, logic is an arch-power that encompasses God and gives reason for god's existence. I.e., God, without logic, could not do any creating nor planning. This appears to refute the idea that God could be the creator of logic. If logic was a precursor to God, then, God is not the sole Creator, but merely a side-effect of some logical process. If, in order to avoid this problem, you state that there is no logical reason why God exists, then it is more likely that there no logical reason why the Universe exists, and that instead of assuming that the organisational force is a 'god', it's simpler and more rational to assume that it is the universe itself. It appears that whether God exists for logical reasons or not a fundamental contradiction occurs. The only answer is that creator-gods cannot possibly exist. Atheism is more logical. This is also true if God is placed "beyond logic". Doing this puts God into the territory of irrational fantasy. To retreat into the corner where logic itself is denied, god-believers have admitted that there is no logical basis for their belief. And if it is said that Human logic is incapable of realizing such metaphysical truths, then this also undermines any argument that can be made by one human to another, for the existence of god.
At this point, it is better to try to understand the idea of God in terms of human psychology. See "What Causes Religion and Superstitions?" by Vexen Crabtree (2013).
“The theist claims that God is the answer. But, then, why is there God rather than nothing?”
"God, the Failed Hypothesis: How Science Shows That God Does Not Exist" by Prof. Victor J. Stenger (2007)2
People who believe in god (theists) subscribe to the theistic idea that the Universe was the work of a creator-god. They say that 'god did it', and although many books have been written about the details, there are fundamental problems with the whole idea that a god created the Universe.
Many argue that all things must have a cause, and therefore, god exists as the 'first cause' of everything else. These people ask questions like "Who do you think created you?" and "Do you think the Universe came out of nothing... who do you think created it?". These types of questions both rely on the "everything must have a cause, therefore God exists" argument. But this argument doesn't work. Examine these points:
No particular conclusion can be drawn from the belief that "everything has a cause". The cause might be something atheistic, automatic, non-conscious, etc. If "everything has a cause, therefore God exists" is a leap of faith that rests upon assumption. Why not, instead, state that: "everything has a cause, therefore karma explains everything?". Additional assumptions are required in order to draw a conclusion from the argument that "everything has a cause".
If god-believers say that 'everything must have a cause' and state that this means that god exists, then, they have missed a part of their declaration out. Their true belief is that "everything must have a cause, apart from God". The term for God as the cause of everything is the 'first cause', so, this is the same as saying "everything must have a cause, apart from the first cause".
God isn't a simple thing; it has thoughts, motivations (to create, to love, etc), it has powers, imagination and its thoughts are themselves ordered logically and coherently so that it can plan things and think about things in a sensible way. In short, God is quite a complicated being.
These two facts combined to produce the more accurate first-cause argument:
The "everything must have a cause" part of the argument must be wrong. It is not true that everything must have a cause. In a causal world, there must always be something that has no cause.
“All causal explanations must have an arbitrary beginning”
“The argument that there must exist a first cause of everything is open to serious doubt as long as we adhere to any simple notion of cause, irrespective of whether the universe is infinitely old, or had a definite beginning in time.”
The conclusion that "everything has a cause apart from one thing" is not only a cornerstone of atheism and theism, but also a generic scientific and religious theory. Many scientists (but not all) think that the big bang was a singularity. This means, it was not the result of an ordered physical law, but was the result of an impossible situation that no laws cover. In other words, it was uncaused. The religious theory that there is a "first cause" is found not only in monotheistic religions such as Judaism, Christianity and Islam, but in atheist religions such as Buddhism too - eventually, everything will be returned to Nirvana and the samsaric cycle of cause-and-effect will end, but, Nirvana itself is uncaused5. All around, the reasoning that "everything has a cause, except one thing" is used to support disparate and contradictory conclusions. The problem is that this logic does not provide evidence as to what the first cause actually is.
So what is the First Cause? Nirvana and the laws of karma, God and its Human personality traits and a mechanistic Big Bang are all multifaceted things. Each one has multiple components and involves various assumptions and various uncaused elements. In other words, the first cause is not a simple thing.
There is a different word for the belief that a complicated self-created first-cause that has a coherent internal logic requires no first cause: atheism. Because if such a complicated thing can exist without a cause, then that first-cause could well be an atheistic Universe, complete with a few internal physical laws. If you argue that everything has a cause except for god, then, you might as well argue that everything has a cause except the universe, and admit that there is no need to theorize that God exists. So if you accept the first-cause argument then it does not prove that God exists, but instead it proves that the Universe could be without a creator at all.
An uncaused God is more complicated than an uncaused Big Bang. When it comes to comparing arguments where there is no hope of actually getting any physical evidence, there is a long-standing heuristic to help distinguish between theories, called Occam's Razor: it turns out that when all evidence is accounted for, the theory with fewest assumptions is more likely to be true. God requires many properties and complexities such as consciousness, thought, personality, creative drive, love, an internal logic ordering its thoughts so that it can think coherently and rationally, memory, etc: All of these properties must have been derived from somewhere. It turns out that God is a vastly more complicated thing than the Big Bang and the fundamental laws of the Universe.
Theists and atheists both believe in some universal laws of logic and/or nature which exist as the first cause. But the theist position adds on a list of personality traits to this first cause, and, calls the result "God". Whether these additional assumptions are warranted or not is hard to prove, hence why we say that the additional assumptions under theism are based on faith. These theistic assumptions include attributes about God: it is all-powerful, omniscient, benevolent, it has memory, it has rational and ordered thoughts running along logical lines, it is emotional, it wants to be worshipped and other particular assumptions of various religions. Even if it was found that the First Cause must be a conscious god, then, it is not reasonable to assume that all those other assumptions are true too. In comparison to all that, atheists make far fewer assumptions about reality, meaning that their position is more likely to be correct.
“The scientist, however, may wish to challenge the assumption that an infinite mind (God) is simpler than the universe. In our experience, mind only exists in physical systems that are above a certain threshold of complexity. [...] While it is possible to imagine a disembodied mind, there must be some means of expression of the pattern, and the pattern itself is complex. So it could be argued that an infinite mind is infinitely complex and hence far less likely than a universe. [...]
According to our best scientific understanding of the primeval universe it does indeed seem as though the universe began in the simplest state of all - thermodynamic equilibrium - and that the currently-observed complex structures and elaborate activity only appeared subsequently. It might then be argued that the primeval universe is, in fact, the simplest thing that we can imagine.”
The additional assumptions of theists are discussed on my page The Assumptions about God and Creation, of Both Theists and Atheists. Its list contains the following items - click on each for a discussion and some comments on the logical problems associated with them:
Some theists argue that God is eternal and was therefore never created. But I find this is an argument that can be used in conjunction with Big Bang theory to prove, again, that god is not likely to exist as a first cause. According to some Big Bang theories there has been an infinite number of cycles of Big Bang / Big Crunch (where the Universe ends in a big black hole after contracting, before exploding again) and that the Universe has existed forever. If it is possible for something to exist forever and not need a cause then it is likely to be the Universe, not God, and once again we can theorize that this is likely to be true because there would be no reason for god if it was true that something could exist with no cause8.
In order to create, to think, God's thoughts must be more than random. To create the universe and its laws, God must be able to think logically. If it can't think logically, then, the laws of the universe were simply random, and the Universe might as well been self-created in an atheistic manner. In other words, for God to exist, God's thoughts must have always been ordered in a logical manner otherwise God could never have created order from chaos.
Kepler, one of the great minds in the history of science, came to similar conclusions about geometry, but didn't go as far as to say that it preceded God:
“Geometry existed before the Creation. It is co-eternal with the mind of God... Geometry provided God with a model for the Creation... Geometry is God Himself.”
In "Cosmos" by Carl Sagan (1995)
Kepler was assumedly counting mathematics and the general rules of the universe as 'geometry'.
This means that logic is a precursor to God. Logic, with its simple relations and rules that lets thought itself be ordered, must have existed independently of God's creative power. God could not have created the logic because requires logical thoughts to do any meaningful creating.
This results in two conclusions:
In theology-speak, the first cause is the description given to the creator of the universe, time, the laws of physics, etc. But it seems that in order for the first cause to be a creator-god, then that god cannot have created logic, and cannot therefore be the first cause after all. In other words, the fact that God needs to think logically in order to create means that God itself cannot be the creator of everything, only of parts of reality. In other words, there cannot be any monotheistic creator god.
If God chose to create anything then it must have had reasons to do so. God's "will" is not random, meaningless, chaotic or thoughtless. This means that these "reasons" are dependent on pure logic and must have driven god to do its very first act of creation. These motivations, this initial logic, will have been dictating God's thoughts from the moment of God's inception. If there was no logic and no motivation, God did not create anything on purpose. In that case, you might as well admit that the Universe created itself randomly, and that no creator God was required.
If god created anything according to a thought-out logical plan, or, if God had a desire to create anything that wasn't pure random chaos, then, god's thoughts must have been framed around logic. This logic allowed god to think and create, and, gave motivation to God. Logic must have been the first cause; but if logic is a requirement for God and existed before God could create, then God cannot be the First Cause, and therefore, creator-god theism is false, and atheism is true.
Some theists will make assertions that god is "outside of outside", "beyond logic", "transcends logic", "not subject to logical limitations" or that "human logic is limited" and other similar argument-stoppers. Although this at first appears to throw all intellectualizing out the window, kick all theology out the front door and firmly garrison the houses of religion from debate, it actually opens up the theist to some further criticisms.
If "Human logic" is insufficient for metaphysics then debating for the existence of God is pointless. Because it is by Human logic, thought and mentality that we arrive at the concept of God in the first place.
If God behaves according to logic that we don't understand (i.e.: Human logic is limited) then God is still behaving according to logic, even if it is logic we don't understand.
To say that god doesn't obey logical rules, to say that God could create a round square, for example, is to say that the abilities of god are abilities that cannot logically exist, making God into fantasy.
"Beyond logic" is a synonym for "irrational", and admissions that beliefs are "beyond logic" is an admission that such beliefs are irrational and logically indefensible.
If God is beyond logic, is it not true that atheists are at least somewhat more rational and logical in their beliefs? It seems to be!
It is not enough to say that "God exists" as the explanation as to why the Universe exists. If a God created the Universe, then, why did it do so? God must have had thoughts - a creative impulse - to create the space-time continuum. Therefore it is the properties and thoughts of God that explain the Universe, not the mere fact that God exists. God could easily exist for all of its eternity, existing in perfection in a perfect world, without creating the Universe. So saying that God explains the existence of the Universe is not the whole story.
“If God has a plan for the universe, which is implemented as part of his will, why does he not simply create a deterministic universe in which the goal of the plan is inevitable? Or better still create it with the plan achieved?”
Unfortunately there have been no comprehensive or compelling arguments as to why God created the Universe. This is a problem that effects not only monotheistic religions like Judaism, Christianity and Islam, but also other religions such as Buddhism: Sages from all these religions have tried to explained why existence is the way it is, complete with suffering and death, but none have given a straight answer as to why any of it needed to exist at all.
The "law of conservation of energy" holds that energy cannot be created nor destroyed, only changed in form. This means that although everything in the Universe may be destroyed, the total energy stays the same. This fundamental law of thermodynamics is one of the most important laws in physics, and is applicable at all scales, from the quantum, to the large scale sciences of engineering and chemistry. It is so important that most physics think that this law can simply never be broken.
Many theists have argued that the scientific laws of thermodynamics, in particular the conservation of energy, imply that there must be a God. If energy cannot be created nor destroyed, they say, then this is proof that the entire spectacle of reality has to be the exercise of a creator God. I.e., a God that creates all of the energy, and then, who creates the laws of thermodynamics. On the face of it, it is certainly one way to explain away the existence of all energy.
But it turns out that the explanation isn't necessary, because the current evidence shows that there is no contradiction to the law of conservation of energy, and it all comes down to gravity12. You expend energy to climb out of an energy well, and, if you add up all the energy of objects and masses and take into account gravity and balance this against the gravitational power of black holes and galaxies, we find that the net value of the energy involved is zero. In other words, if all of the energy in the universe can be accounted for as being matched equally by gravity, it appears that there is actually no created energy.
“Astronomers can measure the masses of galaxies, their average separation, and their speeds of recession. Putting these numbers into a formula yields a quantity which some physicists have interpreted as the total energy of the universe. The answer does indeed come out to be zero within the observational accuracy. [...] The cosmos can [come] into existence without requiring any energy input at all.”
“Physicist Frank Wilczek, who was one of the first theorists to explore these possibilities, has reminded me that he utilized precisely the same language I have used previously in this chapter, in the 1980 Scientific American article he wrote on the matter-antimatter asymmetry of the universe. After describing how a matter-antimatter asymmetry might plausibly be generated in the early universe based on our new understanding of particle physics, he added a note that this provided one way of thinking about the answer to the question of why there is something rather than nothing: nothing is unstable. [...]
[We see that] the total energy of a closed universe is zero, and if the sum-over-paths formalism of quantum gravity is appropriate, then quantum mechanically such universes could appear spontaneously with impunity, carrying no net energy. I want to emphasize that these universes would be completely self-contained space-times, disconnected from our own. There is a hitch, however. A closed expanding universe filled with matter will in general expand to a maximum size and then recollapse just as quickly, ending up in a space-time singularity where the no-man's land of quantum gravity at present cannot tell us what its ultimate fate will be. The characteristic lifetime of tiny closed universes will therefore be microscopic, perhaps on the order of the Planck time, the characteristic scale over which quantum gravitational processes should operate, about 1044 seconds or so. [...]
The very creative cosmologist I mentioned earlier, Alex Vilenkin, who has since become a friend, had actually just written a paper that described in exactly this fashion how quantum gravity indeed might create an inflating universe directly from nothing.”
