Hey, that's QM for you! The Zen Science. (What is the sound of one quark clapping?)
Simplifying (greatly), QM says that nothing exists until it is observed. To be observed, it must exist longer than the Planck time (10<sup>-43</sup> seconds).
Virtual particles exist for less than the Planck time, so - by QM - they don't really exist.
If the Universe is (was) a "soup" of virtual particles and anti-particles being created and then destroying each other within the Planck time, no laws of mass-energy conservation are violated. By QM, nothing has happened.
But, if somehow just
one virtual particle/anti-particle pair failed to destroy each other within the Planck time... Big Bang!
By QM, this creation/annihilation scenario is unstable, requiring a higher energy level than a matter/energy universe to be sustainable. So, the universe is inevitable.
Perhaps the reason there is something instead of nothing is that nothing is
unstable.

Those who are not shocked when they first come across quantum theory cannot possibly have understood it.
