So you could say all those names explain the concept of God.
This link provides some examples: https://www.gotquestions.org/names-of-God.html
Edit: maybe more interesting is the Wikipedia articles listing the names of different kinds of religion: https://en.wikipedia.org/wiki/Names_of_God
Your analagy is akin to The Cloud of Unknowing, a spiritual guide to becoming closer to god by "unknowing", written by a 14th century christian mystic.
Personally I didn't care at all until I had a direct experience that I couldn't explain without "spiritual" vocabulary. And now I'm embroiled in these sorts of debates for fun...
I actually think these academic discussions of "what is god precisely" and "how does it work" only really sway a small subset of people. IMO it's "try these techniques out for yourself and decide for yourself," not "surely this explanation of the entirety of existence will sway you!" I'm with you, I don't think there's a formal text definition of god that ever would have convinced me to "believe." Either you have a notion of a higher power or unitive/connective force and have experienced it, or you haven't and you're working with the evidence you've got (math, the Bible, whatever). Take a few psychedelics or do a bunch of meditation and you'll end up feeling like most practitioners do, which is that you have a strong ineffable experience that doesn't translate well into words. Or don't! God's just a made-up word anyway for an aspect of the universe / human experience that we have a hard time defining (one of my definitions).
What's more interesting is the comment you're replying to actually describes the super-personal nature of God - what Christians call the Trinity. Writings expounding on the Trinity have filled many volumes of Christian theology - it's something far from being "swept under the rug".
As for believers, you can see from this thread that there are many interpretations of God, but on HN they do lean toward the fairly abstract.
Personally, I see our mere existence as proof of God. We can observe God because we are God.
The only thing I've ever really been hung up on is the question of whether God can observe himself to validate his own existence. It's fairly paradoxical.
This is the god of Spinoza. A god that is everything and everywhere is, at the same time, nothing. It is nothing more than the worshiping of the universe.
EDIT: I re-read the post and no, they didn't seem to mean that.
