I don't have any religious faith and was never able to believe in anything supernatural, but i do respect and understand that people who believe in God find themselves in a state of perplexity and this is not fundamentally different to what happens to me.
Our brains didn't evolve to grasp so many complex concepts. And because of our our relation with objects surrounding us, we tend to think that zero and nothingness is the same thing. But if there was nothing and a first particle was created, it would be one particle. If another one was created, it would be two particles. The idea of those numbers existed on a platonic way, even before anything was created. Maybe you're not calling it one and two, it doesn't need to be named, but we can"t erase numbers out of existence, no matter if something exiist, or if there is nothing.
Now lets think about it:
Q: can a universe be created out of nothing?
Standard Answer: yes, all the mass(energy) is positive(unless there is some unknowm form of negative mass), gravity is negative, the sum of the two is zero, then you need zero energy to create an universe and it doesn't demand any explanation for its existence.
Q: is this really out of nothing?
Honest answer: no, we need the laws of Physics to exist in the first place. This isn't "nothing", its a lot of stuff.
Q: Are the laws of Physics eternal?
A: It might be the case.
Its honest to say this is unsatisfactory. even if the wave function of the entire multiverse is eternal, why something would exist instead of nothing? And How any rational eternal being could explain to itself its own existence?
We are becoming cynical and want to avoid ultimate questions. And we pretend the history we tell to ourselves is the whole of reality, because we fear the god of the gaps. But we don't know.
