"As I wrote back in 2018, there are four scientific definitions of nothing, and they’re all valid, depending on your context:

"1) A time when your "thing" of interest didn't exist,
2) Empty, physical space,
3) Empty spacetime in the lowest-energy state possible,
4) Whatever you're left with when you take away the entire Universe and the laws governing it.

"We can definitely say we obtained “a Universe from nothing” if we use the first two definitions; we cannot if we use the third; and quite unfortunately, we don’t know enough to say what happens if we use the fourth. Without a physical theory to describe what happens outside of the Universe and beyond the realm physical laws, the concept of true nothingness is physically ill-defined.

"In the context of physics, it’s impossible to make sense of an idea of absolute nothingness. What does it mean to be outside of space and time, and how can space and time sensibly, predictably emerge from a state of non-existence? How can spacetime emerge at a particular location or time, when there’s no definition of location or time without it? Where do the rules governing quanta — the fields and particles both — arise from?

"This line of thought even assumes that space, time, and the laws of physics themselves weren’t eternal, when in fact they may be. Any theorems or proofs to the contrary rely on assumptions whose validity is not soundly established under the conditions which we’d seek to apply them. If you accept a physical definition of “nothing,” then yes, the Universe as we know it very much appears to have arisen from nothing. But if you leave physical constraints behind, then all certainly about our ultimate cosmic origins disappears.

"Unfortunately for us all, inflation, by its very nature, erases any information that might be imprinted from a pre-existing state on our observable Universe. Despite the limitless nature of our imaginations, we can only draw conclusions about matters for which tests involving our physical reality can be constructed. No matter how logically sound any other consideration may be, including a notion of absolute nothingness, it’s merely a construct of our minds."

Comment: I see outside our universe total void, a complete nothing. Why we are here is up to your reasoning. What is your first cause? That has to exist. We had a demonstrated beginning in time as the CMB demonstrates.
