Millican used my (!) argument against the KCA in his debate against Craig.
"1. There is no evidence that whatever begins to exist requires a cause. All the evidence we have of things beginning to exist are when something is created from rearrangements of other things that already existed.
The closest analog we have to something coming into being from nothing is quantum particles coming into being from nothing, and that causation is random.
There is no evidence that thoughts can bring about physical effects, and Bill is arguing for a mental cause to the origin of the universe.
Even if things that begin to exist IN the universe have causes, it doesn’t hold for the universe as a whole. Bill is committing the fallacy of composition.
Time begins with the universe, but our experience of causation is that it is a temporal process. So if there is no time “prior to” the universe’s beginning, then how can there be a cause to the universe?
It’s possible that there could be something outside our universe that is eternal.
It’s also possible that the Big Bang could be wrong, and this universe could oscillate eternally and not require a beginning.
2. There are cosmological theories that avoid the beginning of the universe by positing a prior period of contraction prior to the Big Bang.
The beginning of this universe depends on general relativity, and that theory breaks down at the level of quantum mechanics.
3. There is no evidence that minds can exist without an underlying physical system. So even if there is a cause of the universe, then it is neither an abstract object nor a mind. It would have to be something else, and not something we are familiar with – we are just not in a position to speculate of what it could be."
