The argument from scale claims that the size of the universe counts as evidence against God. Loftus gives a version of it, though I first learned of it through Nicholas Everitt:
1) If the God of classical theism existed, with the purposes traditionally ascribed to him, then he would create a universe on a human scale, i.e. one that is not unimaginably large, unimaginably old, and in which human beings form an unimaginably tiny part of it, temporally and spatially.
(2) The world does not display a human scale. So:
(3) There is evidence against the hypothesis that the God of classical theism exists with the purposes traditionally ascribed to him.
“The purposes of God” are that God created human beings to be the most important things in the universe.
But the answer here is pretty straightforward: if God wanted the universe to produce human beings he couldn’t have made it on a human scale. As far as we can tell, the only way a universe can even create life is by sheer chance, and the odds are so long against it doing so that you need an immense amounts of time and event-space to be confident it will happen. IOW, it’s precisely because human beings are the pinnacle of creation that the universe can’t have a human scale in either time or space.
This is part of a larger problem that arguments of this sort tend to overlook that the only reason to create some X at all is because you want it to do X-ish or exzy stuff, which means you want it to do it by itself and without the outcomes having to be rigged or monkeyed with. If you’re going to make animals in a universe, you’ll want a universe of the sort that can pull this off, and you’ll want the sort of processes in place that allow for the animals to arise and develop in it. As far as we can tell, this commits us to natural selection and all of its attendant mass extinctions and maladapted structures (like human backs or blind spots or love of fat). These are evils, to be sure, but ones that you are perfectly willing to tolerate under the hypothesis that life is the pinnacle of the universe, and human beings the pinnacle of life.
In other words, arguments like this seem to take it as a live option that God could have just designed animals or *poofed* them into existence, without ever having the universe contribute its own proper causality to the process. But he couldn’t have done this if he wanted them to be natural things, that is, to do natural things and/or to arise from natural causes. This is particularly significant since the only reason to make human beings, or even a universe at all, is because you wanted them to be natural things.
