Question for a Physicist

because the electron is not diminished in any way. So for us non-scientists is this a good reply to use when arguing with those theists that say something cannot come from nothing?

That is not a very good example of something from nothing. But there is a better one and it is this : virtual particles are created from nothing by borrowing energy to come into existence. And then disappearing almost instantaneously leaving only the energy behind. Energy cannot be created or destroyed as that would violate the First Law Of Thermodynamics. A state of nothing however can
not persist because of the uncertainty relation between energy and time. But it does exist as virtual particles are popping in and out of existence all of the time. And so it was not just a single event occurring before the Big Bang. That is merely the earliest example of something  from nothing

I don't think this is really something from nothing, as the fabric of spacetime supports it, and that's something.

To be honest, Krauss' whole point always was that the sum total of the Energy of the universe can be thought of as being zero if you add up the contents and the curvature of spacetime, and could therefore literally originate from a different state of zero energy even without violating conservation of Energy - and giving examples of stuff happening within the universe seems very misleading to me.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
