I am aware that the simplest explanation is usually the best, but in the absence of any scientific explanation for free will and conscious awareness, I have done my best.
Even so, you are, as they say, up the creek without a paddle.
You don't have an 'explanation' since you haven't advanced anything that merits explaining. All you have is a fallacious narrative that you imagine is intelligible in some peculiar 'sciency' way, which you advance as a hook to hang you personal brand of faith on: I suspect this is because you really don't want to come across as being a simple hallelujah merchant which, ironically, in view of your credulity, is exactly how you present.
If you were really on to something you'd have been headhunted by prestigious neurology departments well before now and you'd have a profile on a par with the odious William Lane Craig. You'll no doubt strive to ensure you are suitably ring-fenced in multiple fallacies, but hopefully one day the penny will drop for you yet.
