"Of course, we don't know what "awareness" means scientifically"
Yes we do. You are falling into the same trap as Edwin and many others, by not first differentiating the knowable from the not-knowable. We can only know (be aware) of what is manifest to us (hypothesis being in effect virtual sensing). In other words , physical existence is that form of existence which is all that is potentially knowable to us. Whether we can attain knowledge of all that is doubtful, but another issue, the point is that the potential was there. Whether there is an alternative is irrelevant, because we cannot know it. And knowing it, ie being aware of it, involves the receipt of physical input (supplemented by the hypothesising of input which could have been received had some identifiable physical issue not prevented that). The subsequent processing of this input received is irrelevant, as that is not physics. The utilisation of representational devices to express this knowledge is another matter.
