Created reality consist of both, physical reality and created spiritual beings.
I would rather state:
The physical reality consists in events which:
Some physical phenomena (relativistic-local phenomena) can be explained by causal links, i.e.: signals propagating non-faster than light. The velocity of light c bounds propagation in space-time and limits what humans can cause at a distance.
Other physical phenomena (quantum nonlocal phenomena) cannot be explained by signals propagating in space-time. In this sense they require action coming from outside space-time. These phenomena have useful applications in cryptography and quantum computing. However, they do not allow us “phoning faster than light”.
Important: To the extent that space-time is quantized (“pixelated”) even relativistic-local phenomena cannot be reduced to information stored in space-time.
Usually one refers to physical reality also as material reality. Thus, we are led to conclude that material reality cannot be exclusively explained by material causes: To explain what is material one has to invoke a non-material reality or, as you say, “a spiritual dimension”.
Human ability is undoubtedly limited by the velocity of light.
But there is another important limit:
In the ordinary world we live in, macroscopic visible objects are not in Quantum Superposition. This makes it possible to have reproducible, observer-independent events, and (in your wording) “to give humans the certainty of a rather stable universe”.
However, Quantum Superposition can extraordinarily involve macroscopic visible objects. Then observer-dependent, one-off events, may happen that is, miracles beyond our operational capabilities.
This means that Quantum is more than Physics.
I would say: The spiritual is as much real as the physical, and can act upon space-time reality to produce, for instance, meaningful pieces of speech or text, as those we produce in writing our comments.
However, Evolution lays the groundwork for assigning rights: The deletion of intermediate varieties allows us to clearly distinguish human beings from non-human animals. In this sense Evolution plays an important role to connect the physical and the spiritual.
Additionally, what makes humanity unique and precious is the Incarnation of God. So Evolution can be considered to aim the body God prepares for His Son, i.e.: Jesus Christ’s body.
