There's 40 or so definitions of "consciousness"; and even Christians (let alone all the other religions) don't all agree with each other about what does and doesn't have it and what the implications of this are.
But we can say there's no gap in physics into which unknown forces could manifest actions on our bodies. (This is different from saying "proves the absence", it is only that you'd need to come up with something as powerful at explaining the world as all known physics in order to create room for such a thing).
"Meanings Attributed to the Term 'Consciousness' An Overview", Ram Lakhan Pandey Vimal.
Abstract: I here describe meanings (or aspects) attributed to the term consciousness, extracted from the literature and from recent online discussions. Forty such meanings were identified and categorized according to whether they were principally about function or about experience; some overlapped but others were apparently mutually exclusive — and this list is by no means exhaustive. Most can be regarded as expressions of authors' views about the basis of consciousness, or opinions about the significance of aspects of its contents. The prospects for reaching any single, agreed, theory independent definition of consciousness thus appear remote. However, much confusion could be avoided if authors were always to specify which aspects of consciousness they refer to when using the term. An example is outlined of how this can be done (using a 'PE-SE' framework).
