I look at it this way. Unless and until God sees fit to explain more fully, I am free to have the perspective I find most logical and reasonable to my understanding. So, in light of that, I would make somewhat of a comparison. Let us say I have a wonderful mortal father (that wasn't the case I'm afraid, but let's pretend). No matter what I do throughout my life, that man will always be my father. That is a fact of biology that nothing can change or alter. So no matter what I do and no matter how many other wonderful fathers may exist out there in the world, that changes nothing for me, because my father is and always will be the father of my mortality. No one can replace him or take that position from him. Also I, as my father's child, even if I were to become a parent in my own right (that was not the case either, but let's pretend) and no matter how good and wonderful a parent I may become to children of my own, I would still hold my father in deference as the father who gave me mortal life, and my children, who would likewise give me deference as their parent, would hold my father in deference as their grandfather, and so on through each generation. So no matter how many, or how few, fathers (or grandfathers, etc.) may exist out there, it would not change the relationship I have with my father, nor would it change for my children, and so on. As I see it, that would be the reasonable and logical patriarchal order of things, not only in earth, but also in heaven. So, with God the Father being my Eternal Heavenly Father and God, nothing can change that, just as nothing can change the reality that Jesus Christ is the author and Father of my eternal salvation. No being can, nor ever could, replace, supplant, or usurp that position, because it's a reality in fact. So, not knowing all there is to know about Godly things and the heavenly order of things, it matters not to me if there are other beings in existence that do the things God Himself does. Nor does it matter if I might one day reach a point where I could also do things like my Heavenly Father can. I have no problem theologically with that idea, because nothing can change the reality that God the Father is literally my Heavenly Father and God so nothing can or will ever change that truth. Therefore I find that sufficient for my present understanding and unless and until He sees fit to explain more fully the details of eternal things, I'm satisfied with holding that perspective.
