I have answered by indicating that the free will of the human soul can invoke a conscious choice.
Which isn't an answer to the question.
This is not determinism in the physical sense because the cause of the invocation of the choice lies in the spiritual awareness of the soul.
You weren't asked about determinism
in the physical sense.
I am not God, so I do not claim to know how the soul invokes a conscious choice.
At last! Okay, so you don't know.
The problem with that is that you started all this out by saying that a physical explanation for our conscious awareness and "free will" was not possible because of physical determinism and now you are saying you haven't a clue what the alternative is.
Further, there aren't many places for you to go from that. Either you have to ask us to accept an unknown that is illogical (presumably on the basis that it's beyond "human logic" or a "mystery"), which undermines the whole idea of a logical argument for it in the first place. Or you have to accept that "free will" can only be made up of deterministic (and possible random) processes in the soul, which undermines the argument that it can't be physical.
Either way, your whole argument for god on the basis of the necessity of the soul has collapsed in a heap of contradictions...
