Quantum Field Theory is not as you are describing it. It is not about creating something from nothing.
I mentioned QFT as a specific part of quantum mechanics applied to expand on how there happens to be something rather than nothing.
In that regard it most certainly does give insights about a universe from nothing.
More insights If you don't mind me saying
than the magic imaginary sky wizard notion that you support plus all the associated horseshiite that goes with it .If a God can be eternal then so can a Universe.
[..] the physical universe can perfectly well be self-contained; it doesn’t need anything or anyone from outside to get it started, even if it had a beginning. Sean Carroll
He is going to be more right about any of this than you are
