Let's start with your original assertions.
It is possible for matter to have a beginning. In a closed universe the gravitational energy which is always negative exactly compensates the positive energy of matter. So the energy of a closed universe is always zero. So nothing prevents this universe from being spontaneously created. Because the net energy is always zero. The positive energy of matter is balanced by the negative energy of the gravity of that matter which is the space time curvature of that matter. There is no conservation law that prevents the formation of such a universe. In quantum mechanics if something is not forbidden by conservation laws, then it necessarily happens with some non-zero probability. So a closed universe can spontaneously appear - through the laws of quantum mechanics - out of nothing. And in fact there is an elegant mathematical description which describes this process and shows that a tiny closed universe having very high energy can spontaneously pop into existence and immediately start to expand and cool. In this description, the same laws that describe the evolution of the universe also describe the appearance of the universe which means that the laws were in place before the universe itself.
You can't even be honest about what my first post was, so why should anyone expect you to be honest about quantum mechanics which you don't even understand. In the quantum universe there is no such thing as nothing.
My first post:
Actually, it is the bible that claims that no thing (God) created everything from nothing. Science proved that there never was nothing and there will never be nothing, the First Law of Thermodynamics AKA The Law of Conservation of Energy.
Even better. The inflation model shows it did. Just like the 2nd Law of Thermodynamics shows that it is impossible to have a cyclical universe with no beginning.
Already debunked at least a dozen times in this thread.
Be sure to let Guth know about that, lol.
He already knows! Even Vilenkin says you are full of it!
Guth's Grand Guess | DiscoverMagazine.com
Start, Guth says, by imagining nothing, a pure vacuum. Be careful. Don't imagine outer space without matter in it. Imagine no space at all and no matter at all. Good luck.
To the average person it might seem obvious that nothing can happen in nothing. But to a quantum physicist,
nothing is, in fact, something.

INFINITE INFLATING UNIVERSES
So far, what inflation theory predicts, the observable universe has reflected. But cosmologists
Andrei Linde, Alexander Vilenkin, and others have run with inflation's premises to step beyond the bounds of what we can see or measure. They speculate that the decay of the false vacuum—which, according to the inflation theory, created the matter of our universe—does not happen all at once. While some regions decay into universes, other regions keep expanding and creating other universes. Residual false vacuum from the creation of those universes creates still others, indefinitely. Linde and Vilenkin call this
"the eternally existing, self-reproducing inflationary universe." Guth contends that this scenario is not only possible, it seems like a sure thing. "If a biologist discovered a bacterium that belonged to no known species, she would presumably invent a new species in which to classify it," Guth wrote in his 1997 book,
The Inflationary Universe. "However, even though only a single specimen of the new species had been found, she would undoubtedly assume that it was the offspring of a bacterial parent cell."
Guth predicts that "any cosmological theory that does not lead to the eternal reproduction of universes will be considered as unimaginable as a species of bacteria that cannot reproduce."
