The evidence you and many on this forum try to ignore is your own capability to guide the contents of your conscious mind to formulate reasoned arguments and draw validated conclusions.
Nobody is denying that happens; the disagreement is on where that 'conscious mind' comes from, what it constitutes, how it functions. You posit some extra-dimensional 'driver' on the basis, so far as we can tell, that you really, really don't like the implications of the deterministic explanation, but you've neither offered anything to support your own contention nor to undermine the counterpoint.
The problem you fail to acknowledge is the limitations of what can be achieved by physical reactions alone without any means of conscious guidance.
We can't acknowledge anything until you explain what it is that you think they are. So far the 'limitations' appear to be in your capacity to accept the possibility, and nothing more. You've not made an actual argument that needs to be acknowledged or countered, you've just repeated asserted 'free will because souls'.
In the materialistic scenario you have to presume that our conscious awareness is an emergent property of material reactions.
Yes.
So the material reactions responsible for our conscious awareness will have already occurred before our awareness kicks in.
Yes. There is, albeit limited, evidentiary support for this supposition, as well.
Awareness will be the end result of the physical brain activity with no feasible means to interact with the reactions from which our conscious awareness emerges.
Not exactly. The awareness provides a feedback mechanism which could conceivably feed into the subconscious 'processing' and update conclusions, but that process is not 'guided' by us, that process is us being us.
So how I am currently able to contemplate this scenario and draw these conclusions without any conscious interaction with the thought processes involved?
Because the formative notions to which you've been previously exposed have shaped the architecture of your brain in such a way that your subconscious can't parse those links, the 'training' it has undergone in your life of exposure to ideas does not equip it to put those ideas into a framework that holds together with the precepts that are already foundational to you.
I am constantly being accused of personal incredulity - but how can it be labelled "personal" if my apparent incredulity is generated by unavoidable material reactions beyond my conscious control?
Because it is YOUR subconscious and conscious mind failing to accept that notion - that's what personal is, specific to you and your mental activity.
I am not appealing to magic. I am just witnessing to our God given gift of free will which allows us to think, to contemplate, to draw valid conclusions, to analyse, to choose between good and evil, to believe, to cast judgement, to pray, to worship, to love ....
If it's not something that has a naturalistic explanation, and so far what you've suggested doesn't, then whilst calling it magic might be a tad comically pejorative, what's a better phrase? Does supernatural have a better vibe? Divine? Why should it get special treatment when, say, pagan rituals to influence human behaviour would presumably be called 'magic' without any pushback?
Remove this gift and we would be driven entirely by automated reactions generated from biological instincts and learnt experience with no will of our own.
There is no gift. There is nothing to remove. There are just scales over your eyes that need to be shed.
