So if you're going to postulate that God created the universe, but that God himself is eternal, why not just skip the extra step and say that the universe is eternal? Logically it makes just as much sense and it is a much simpler argument.
We all see even in our own lives how creatures (the personal) can create the "its" (art, literature, structures, etc.). How many of your "its" do the reverse? How often has your painting given birth?
It's folks who keep wanting to put the "it" -- the impersonal -- as the original source -- who keep reversing what we observe all the time. The personal begets both the personal and the impersonal; I don't see my microwave doing spin-offs just because we alter one simple gene in its make-up.
But, I suppose, given enough time, my microwave will eventually begin to do cartwheels on its own. Keep the faith.
