@Susmariosep,
I see you are seeking an intelligent discourse.
I don't believe I am the best when it comes to critical thinking, but I will do as best I can.
I believe that the current sensory layer that we exist in is just that - a layer. A sector on a grid of dimensions that overlap each other. This is where String theory (superstring theory) comes into play, as well as the world of quantum physics. When the Bible is talking about the spiritual realm, it is likely referencing a layer on the grid in which quantum beings (or beings made of something yet to be discovered) travel and reside. And because they (the realms) all overlap each other, that means wherever you travel in that other realm also equals where you travel in the physical realm, or the sensory realm, if you travel a certain way* *perhaps this only applies to one realm at which they can switch to, and not applicable to others, if there are any (I am, of course, not sure.)
Thus, the creation of the physical universe was just the formation of another layer of energy, and doesn't scientific observation profess that energy always has been and always will be, flowing into and out of form? This concept of layering explains how, in the Bible, angels can materialize, levitate, and affect physical matter in this realm and not get affected by anything in it (such as that one time a single angel destroyed an entire army of Assyrians: Isaiah 37:36 reads:
"36 And the angel of Jehovah went out and struck down 185,000 men in the camp of the As·syr′i·ans. When people rose up early in the morning, they saw all the dead bodies"

Also, taking into account this fact, it is important to keep in mind that God is in the very particles to which we are made up of. He is quite literally the Boson field which gives particles mass and shape, and as such he is in effect the (operator) of the universe, and his holy spirit is simply energy in the purest form, whatever that may be.
This is just a theory of mine based on what I have studied and meditated upon, but perhaps it contains some merit. Let me know, please, what you think.
