Frankly, I have a problem with the demand that God's acts be unnatural. That just doesn't add up to me. Not that he can't intervene in ways that seem unnatural, and accomplish things that are unusual, but to me it is all miracle.
The only things we have to go on are what we observe and our admittedly limited reasoning abilities.
It seems to me that we can reasonably ask what we might expect the universe to look like if it was created for us by an omnipotent omnibenevolent God of the Abrahamic tradition. From this point of view, it looks like massive overkill - a vast universe, almost all of which we'll never be able to access, and almost all completely hostile to human life. There are also a number of oddities that appear quite unnecessary, such as the very low entropy at the big bang. One could also argue that an omnipotent creator would not need to fine-tune any physical parameters. We would not expect to see the select creatures, for whom all this was specially created, showing multiple lines of evidence of having common ancestry with the other creatures over which they're supposed to have dominion, nor the degree of unnecessary suffering the sentient creatures are subject to.
On the other hand, if we, and the creatures we share this planet with, and the universe itself, are the products of natural processes that are the products of relatively simple rules, and we are just an incidental feature of a universe not designed especially for us, the features described above fit that model very well.
Of course, it's always possible to find anthropomorphic reasons why God might want to do things this way rather than that way, so that they look less like divine creation and more like natural development and evolution, and it's always possible to say, 'God works in mysterious ways', but the former is circular argument and/or special pleading, and the latter is an admission of ignorance that invalidates reasoned argument altogether.
If we're going to reason about the origins of the universe based on what we see, the evidence, prima facie, does not suggest the omnipotent hand of a deity creating a universe for us, but a universe of unknown origin, developing according to natural rules, that gave rise to life on Earth from which we evolved
¯\_(ツ)_/¯
YMMV
