Theology is as much a branch of human knowledge as the natural sciences. And while science is continously re-evaluating its models for a better understanding of the physical world, philosophers and theologians are continously re-evaluating the nature of their faith.
You are correct in saying that it is exactly the same thing -- more accurately, different fields of inquiry proceeding from different premises about two different aspects of the SAME THING.
As for the expanding universe, we are confronted by two different points of view -- spatial expansion attributed to the negative tensile energy of a curious nothingness, on the one hand, and a continuing process of creation initiated long ago on the other.
And I would suspect that the idea of a creative nothingness, especially within the scientific community, would have been preposterous had it not become intellectually fashionable to speculate the nature of nothingness and all that absurd pseudo-religious nihilist crap concocted by certifiably insane people (like nietzche) to begin with.
Now, I ask, who exactly is spreading bile around like candy -- the people who believe that there is some rational purpose in creation, a purpose that is good, or the people who, having found no particularly good reason for their miserable existence (and stupidly believe that there isn't any in others as well), believe everything is hurtling headlong to a complete and irreversible state of oblivion?
Let me guess -- you need to unleash that primal will to power residing in everyone's dank and dark psyche, destroy all vestiges of rational and logical restraint, and follow it like an instinct-driven beast to whatever sh1t-hole it leads us. Thus says zarathustra.
Pardon me if I don't follow suit.
