Is the Subject Matter of Science Limited?

There's a lot of life left and then the empirical only model. The fact that you're talking about God or some spiritual entity or consciousness is not doesn't rule your hypothesis out of court. What is needed is for there to be some connection to things that can be observed since that's the only kind of information you're allowed to use. I do for and against your hypothesis, so you do need that kind of connection but if there is that kind of connected, I would count that as scientific.
