Is God wasteful, according to geocentrist models of the universe?

The economy of God is unbeatable and without peer, as evidenced for example by the fact that, even as semiconductor design and engineering is approaching atom-scale electronics, human and animal brains are still orders of magnitude more energy-efficient and capable than the world's most sophisticated microchips. God has also succeeded at creating enormous fusion reactors the universe throughout while scientists still struggle to get hints of the feasibility of such technology under carefully controlled laboratory conditions. This question is for young earth creationists who believe that all other stars, galaxies and objects in the cosmos were created attendant to the Creation of this Earth, and that there is no life on other worlds (other than perhaps spirits or eternal beings pertaining to, or known by the people on this Earth), or that this Earth is otherwise unique in terms of theological significance or its place in the universe in some pre-eminent way. I refer to these beliefs as "geocentrist" models because they make everything in the universe effectively revolve around this Earth and its purposes. I do not say they deny that the Earth revolves around the Sun, but they still make everything in the universe effectively accessories to this Earth and its Creation. What reasons do they give for why God with such mind-boggling extravagance would create so many other galaxies, stars, solar systems and even planets--given for example the gargantuan amounts of energy that each star outputs--if not a one of them sustains life of its own, or has any other purpose except towards this Earth and its populace? That would actually make life on Earth less energy-efficient than the most primitive creations of mankind, by a large margin. Obviously there are other ways to measure this, but again, why waste the vast, vast, vast (with many zeros added on for good measure) majority of starlight and creative effort on something so far away that our telescopes cannot resolve 99.999999% it to more than a mere point of light? God is doubtless generous, with trillions of photons devoted to striking our eyes each second, and efficiency isn't everything, but is He wasteful? This is a natural question asked by those who ponder why God would create so many quintillions of stars, but only one with life in its system? Why would He break the pattern of sustainable life on other worlds, forfeiting the opportunity to have and redeem quadrillions of quintillions more of His children, when the resources are clearly there and already organized to sustain life? Or if they are not organized in such a fashion to sustain life, surely He has the intelligence to do it--is there some other limitation or reason why, other than simply that He can? To be clear, this is not *my* question or criticism, but rather is a natural question or criticism levied by some secular scientists and engineers regarding common interpretations of Genesis. They might have a point, not against God's ways, but that should help us to correct our own misunderstandings. What can we say that will address the criticism and instruct our own ways?
