It seems to me that, mainly for epistemic reasons, god is a mystery which will never be solved, although -- given human nature -- many people will endlessly seek to arrive at firm convictions about god.

BONUS QUESTION: Are there benefits to being uncertain about god?
This goes straight to the basics ─ what does the question actually mean? What is 'God' or 'a god'?
In particular, are we talking about a real entity ─ one with objective existence ─ or an imaginary one?
We have no definition of 'God' such that if we found a real candidate we could tell whether it were God or not. This tends not to be a problem because candidates are all but never proposed, at least in the West. For me those two facts are related, and greatly reinforce the view that God is imaginary.
Also, in my view, '(objective) reality' is the same thing as 'nature'. If God is said to be supernatural then by definition God is not in nature, ie is not real, and so the only thing God can be is imaginary.
So if we're looking for a real God, the first thing we need is the definition a real God. Without it we have no idea what we're talking about, and thus we have no idea what we're looking for.
If God is imaginary then no such problem arises, of course, since God can then be anything the individual cares to imagine.
The bonus question asks if doubt about God is good or bad for religion. I'd have said that the aim of religion is to have everyone on the same page about God, and that doubt is thus automatically a problem albeit a common one.
