The cosmological arguments for God's existence are predicated on the first principles of ontology, i.e., the fundamental facts of existence per the imperatives of logic. Many fail to appreciate the intermediate premises of these arguments, particularly those of the KCA.
The following includes my own sub-premises for the first premise and my summary argument for the conclusion:
The Kalam Cosmological Argument (Horizontal Argument)
1. That which begins to exist must have a cause of its existence.
1.1. Something exists.
1.2. Existence from nonexistence is absurd.
1.3. Something has always existed.
2. The universe began to exist.
Argument based on the impossibility of an actual infinite.
2.11. An actual infinite cannot exist.
2.12. An infinite temporal regress of events is an actual infinite.
2.13. Therefore, an infinite temporal regress of events cannot exist.
AND
Argument based on the impossibility of the formation of an actual infinite by successive addition.
2.21. A collection formed by successive addition cannot be actually infinite.
2.22. The temporal series of past events is a collection formed by successive addition.
2.23. Therefore, the temporal series of past events cannot be actually infinite.
3. The universe has a cause of its existence.
3.1. If the cause of the universe's existence were impersonal, it would be operationally mechanical.
3.2. An operationally mechanical cause would be a material existent.
3.3. The causal conditions for the effect of an operationally mechanical cause would be given from eternity.
3.4. But a material existent is a contingent entity of continuous change and causality!
3.5. An infinite temporal series of past causal events cannot be traversed to the present.
3.6. Indeed, an actual infinite cannot exist.
3.7. Hence, a temporal existent cannot have a beginningless past.
3.8. Hence, time began to exist.
3.9. A material existent is a temporal existent.
3.10. Hence, materiality began to exist.
3.11. The universe is a material existent.
3.12. Hence, the universe began to exist.
3.13. Hence, the cause of the universe's existence cannot be material (per 3.10.).
3.14. Hence, the cause of the universe's existence cannot be operationally mechanical (per 3.2., 3.10.).
3.15. Hence, the eternally self-subsistent cause of the universe's existence is wholly transcendent: timeless, immaterial and immutable (3.13.).
3.16. The only kind of timeless entity that could cause the beginning of time sans any external, predetermining causal conditions would be a personal agent of free will (per 3.3., 3.14.).
3.17. Hence, the eternally self-subsistent cause of the universe's existence is a personal agent of free will.
The Vertical Cosmological Argument
- If something exists, there must exist what it takes for that thing to exist.
- The universe—the collection of beings in space and time—exists.
- Therefore, there must exist what it takes for the universe to exist.
- What it takes for the universe to exist cannot exist within the universe or be bounded by space and time.
- Therefore, what it takes for the universe to exist must transcend both space and time.
Ahh. So basically, you re-wrote William Lane Craig.
The Existence of God and the Beginning of the Universe | Reasonable Faith
It is in the various “Supernatural Design” arguments that the religious extremists show their inherent and fatal flaws in the grandest sense. If one can think critically and is observant, one can see within every argument of apology and theism the standard formula stated below:
A. Claim that everything falls under your assertion
B. Posit god as the explanation of your assertion
C. Exempt god from "A"
Is that your intention? To defend the Kalam Cosmological Argument? How droll.
For sadly, the KCA tells us nothing about the character of the gods it claims to demonstrate. It is particularly silent on such “god’s” omniscience.
And that is the weakest of the KCA's already weak contentions. The KCA’s presumption, like so many of the fatally flawed arguments for gods, rests on “timelessness”.
Sadly, the excuse of "timelessness" when considering the omniscience or omnipotence of the gods remains simply that, an excuse.
In fact, it creates further problems for you, since it puts even a finer point on the inability of an omniscient (or timeless) entity to act with volition.
“Timelessness” is the essentially
the exact same thing as “omniscience.” It serves theologically both as a mechanism explaining the capacity of various gods to know everything, and as a tool for trying to short circuit the major logical flaw of all the many versions of cosmological arguments for their existence. But its own implications are equally (in fact identically) problematic for omnipotence.
For while “timelessness” might be a third assumed characteristic of various gods, it is not a possible assumption
for the creation. We all exist rather firmly imbedded in a temporal context that (following the second law of thermodynamics) moves inexorably (though not uniformly) in one direction, as does everything else within the known universe. Whatever the gods “experience” of that temporal context might be is irrelevant since all consequences of choice, decision, action or plan can only take place within
this one.
This is particularly critical when considering the Christian “salvation schemes,” or the concept of a “test on earth.” These can only be meaningful in a temporal context, and for the gods to be timeless is to eliminate the possibility that such “tests” are real. For while humans might go through the motions of “justifying” the gods eventual judgment for an eternal fate in hell or in paradise, for the gods, the results of the test have always been known, certain, and irrevocable. There is no test at all, only the inexorable performance of a prewritten script with a predetermined outcome that was ultimately and arbitrarily assigned by the gods, without any input from human intention or behavior.
Further, for the gods to be timeless also requires logically that everything else also be timeless. With no experience of time, the gods knowledge, experience, decisions and actions must also be timeless. There can never be a “time” in which the gods were not the creators of the universe, since that would means there was a “time before the universe was created” during which the gods existed but the universe did not. Of course, “timelessness” proscribes such a possibility. Therefore, the universe (and everything in it) must also be timeless, and the very concept of “creation” as an effect of a “divine act” is rendered meaningless.
Rather than the OP having taken place under one mistaken preassumption, it already has fully subsumed and considered “timelessness” within its consideration of “omniscience.” It turns out to be just another example of the internal contradiction and self refutation of the Abrahamic concept of god.
