Yes.
Everything in the physical sciences during the past century points to an undeterministic reality.
You have heisenberg's uncertainty principle, the chaos principle and the copenhagen interpretation of quantum mechanics.
Surely, schrodinger's cat couldn't be alive and dead at the same time!
No one is seriously contemplating that causation doesn't work, or that it does only some of the time.
The fundamental distinction here is between DETERMINISTIC AND NON-DETERMINISTIC causes. When I mentioned the law of inertia, it qualifies 'UNLESS AN OUTSIDE FORCE ACTS UPON IT'. And this outside force not only means a force outside the body, but outside the laws of physics itself -- hence the logical relationship between an action and will.
Free will implies choices. And choices, however complex they may be, implies 'to act or not to act'. Intutively, we know that these fundamental choices are not governed by any physical law, only our individual wills.
And when the choices involved in cosmology is for the universe to exist or not exist, then it is, for all intents and purposes, an act of creation -- hence creative will.
