Can't say as I agree with you on a couple of points.
Possession of consciousness.
That would imply, that which creates, reflects, and is by its nature spirit, could be contained by an idea/identity outside of that.

Science of Spirit being unknown.
That science is as old as humanity. One need only look to find the reflections of that science upon history in the words of the enlightened scientists of the past and present.
