The only meaningful question that I think could be embedded in this is something like 'Is there some secret/lost book of the bible that only eggheads, nerds, and Vatican insiders know about that most of the population doesn't' - not really. The only place you'll find attempts at answering these kinds of questions is in places like the Gnostic texts, and even there you really come in contact where their complex cosmologies still sit on an ultimate unknowing no matter how fancy the array of objects, hierarchies, or deities gets. This and, IMHO, by the time you're looking at Gnostic texts you're probably ready to look at pretty much everything else as well.
The bible is incredibly collapsed on this point, and you're really not given much of anything to go on aside from the notion that there are metaphysical complexities hinted at (such as in Ezekiel or Isaiah) but that it's machinery we wouldn't understand, it's not our species' stomping grounds, and so it's a moot point.
I'm not sure which approach is better - ie. pelting someone with the complexities of the Tripartite Tractate, Pistis Sophia, or things like Rudolph Steiner's strapping cosmologies to prove to people that it's turtles all the way down (or up) or whether it's better to just say 'don't waste your time unless something 'up there' solicits your involvement'.
As for 'who made god', if you're not okay with 'humans did - God is a repository for governance that we want off-limits to human tampering' then it's like asking 'what made fields'.

I use the word "love" here not merely in the personal sense but as a state of being, or a state of grace - not in the infantile American sense of being made happy but in the tough and universal sense of quest and daring and growth.” - James Baldwin
