It was previously thought that things could supernaturally form from matter. For example, if you put cheese and rags in a box, baby mice would spontaneously form from the rags in the box. Obviously, people built tighter airtight iron boxes, and found that mice only came from mice. I never heard that Pasteur disproved supernatural. I only heard unknown. Science doesn't have any trouble with the unknown today. Why does it have to presume there are no unknowns to be science in your theory?
Shalom.
