This is William Lane Craig's Kalam argument for a personal creator God -
Whatever begins to exist has a cause
The universe began to exist
Conclusion: The universe has a cause.
Next argument:
The universe has a cause
If the universe has a cause
A creator of some kind exists.
This creator is without beginning. It which cannot change for that which changes can begin to change itself but we are saying we don't need it to have a begin of any kind or form. It is not subject to time. It is eternal which means it is unchanging and past and present and future do not relate to it.
If it is a personal creator then this being spans the universe and is not a material being.
Therefore it is reasonable to suppose that:
An uncaused, personal Creator of the universe exists, who spans the universe is beginningless, changeless, immaterial, timeless, spaceless and enormously powerful.
This does not claim to prove this kind of creator exists but to show it is sensible to suppose it does. You can regard it as proven that there was a cause even if you can't say what it is.
REPLY:
The Kalam Cosmological Argument assumes that whatever begins to exist has a cause.
However, our intuitions about causation are based on ordinary, forward-moving time. If time itself is non-linear at the origin of the universe—if, for example, “time warps” or paradoxical loops are possible—then causation may not work in the straightforward way we assume.
In physics, certain solutions to Einstein’s general relativity equations suggest that time can, in principle, loop back on itself. For example, the Gödel Universe describes a rotating cosmos in which closed timelike curves exist—paths through spacetime that return to their own past, creating a kind of “time loop.” Similarly, a rapidly spinning Tipler cylinder or a traversable wormhole with relativistic time dilation could allow an object to travel into its own past. These theoretical constructs show that under extreme conditions, the structure of spacetime itself could permit loops in time, leading to paradoxes analogous to the classic grandfather paradox, where causality becomes non-linear and counterintuitive.
Just as time travel within the universe leads to paradoxes (e.g., the grandfather paradox) or self-consistency constraints, it is conceivable that the universe’s beginning could involve causal structures that are mysterious or paradoxical.
Therefore, attempting to fully explain the universe’s origin—such as by invoking God as the first cause—may overreach our understanding. The beginning could involve forms of causation or temporal structures that are fundamentally beyond human comprehension.
Despite centuries of theological, philosophical, and scientific inquiry, there is no definitive logical proof, empirical evidence, or experimental test that confirms the universe actually began at a specific moment. The notion of a beginning is largely inferred from cosmological models and metaphysical assumptions, but these models rely on extrapolating known physics beyond observable limits. Theology may propose a creator or first cause, and philosophy may argue for causation, but neither provides a testable demonstration. Even modern cosmology, including the Big Bang theory, describes the universe’s evolution from a hot, dense state without offering a direct observation of a true “beginning.” In short, the idea that the universe began at a precise point in time remains fundamentally speculative—a well-educated guess rather than established fact.
THE THREAT TO SCIENCE
Either one prioritizes God’s personality or God’s creative power.
Prioritizing personality emphasizes relational significance rather than cosmological explanation.
Prioritizing creative power emphasizes ultimate causation rather than relational significance.
Therefore, the choice of emphasis reflects personal or philosophical bias but does not refute the logical necessity of a first cause as argued in the Kalam Cosmological Argument.
Rethink this argument in light of - what if I had to literally forget one of them.
