1. Here is the sentence before your sentence and your sentence together... I have bolded and underlined the
s to give your sentence proper context.
"As recent advances in cosmology suggest, the laws of gravity and quantum theory allow universe
s to appear spontaneously from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going."
2. I noticed you ducked the important part again....
Now given the fact you are making the argument that gravity can create a universe...in a non multiverse environment.... please give us the science and links supporting your conjecture.
I will give you a hint... one guy made the argument decades ago and famous scientists have been knocking it down ever since. Because as Hawking has stated you need 3 things to make a universe... it not nothing...
Hawkings top down cosmology speculates gravity molds the histories of the universe an observer would be in... but it really does not make a universe.
here is the paper I have presented to you many times before... explaining this.
In these two paragraphs Hawking will disabuse you of all your misrepresentations.

Here hawking explains that if you work with the standard model that we have the universe is carefully fine tuned or you have to invoke the notion of eternal inflation (infinite universes.)

In fact if one does adopt a bottom-up approach to cosmology, one is immediately
led to an essentially classical framework, in which one loses all ability to explain
cosmology as central question - why our universe is the way it is. In particular a
bottom-up approach to cosmology either requires one to postulate an initial state of
the universe that is carefully fine-tuned [10] - as if prescribed by an outside agency or it requires one to invoke the notion of eternal inflation [11], which prevents one
from predicting what a typical observer would see.
Here - Hawking disabuses Stu of his other bullshit. We see Hawking clearly speak of alternate universes.

Here we put forward a different approach to cosmology in the string landscape,
based not on the classical idea of a single history for the universe but on the quantum
sum over histories [12]. We argue that the quantum origin of the universe naturally
leads to a framework for cosmology where amplitudes for alternative histories of the
universe are computed with boundary conditions at late times only. We thus envision
a set of alternative universes in the landscape, with amplitudes given by the no
boundary path integral [13].
