I agree that the universe isn't expanding as such. Steady state is another thing entirely. By analogy: I get up in the morning and see substantially the same face I saw the day before, but time has passed, nutrients processed, motion through space without and space within has occured, memories formed, cells grown, apopted, shed. If I remain in a true "steady state", I am not alive.
Likewise, "It still moves" in the universe, be it Gallileos planets in retrograde motion, distant galaxies or fish in the sea. Change happens continuously. Life and existence ends if change stops... Yet still then life goes on and planets and stars are born, evolve and die.
What sort of creationists do you speak of? Biblical creationists have an infinitely mutable readymade convenient all purpose fudge factor called "God" which can easily be used to conveniently account for any observed fact, or unobserved hypothecation.
Those who speak of the natural creation of the universe attempt to account for observed phenomena with natural hypothesis and theory. At times, in order to maintain consistency with observations, theories change, and new hypotheses are plaused. The one thing that doesn't stay the same is the universe... even the ideations of it's sentient inhabitants change. The so called " steady state" theory of universal evolution postulates, not a constant, unchanging universal plenum, but cycles... Though the overall content in those theories is referred to as "steady state", that theory too has change accounted within it. The only plausible steady state is the atheists view of the process of the mind after death.
