In fairness, it's historically contingent. Until the renaissance, the most widely accepted view was that the universe was confined by a spherical sphere of the fixed stars, beyond which was heaven, the size and shape of which was anyone's guess. The telescope gave us the means to see the 'universe' in more detail and it became clear that the 'fixed stars' were neither fixed, nor all the same distance. So in practice, the 'universe' came to mean the Milky Way. Greater resolution showed that fuzzy patches of light, like Andromeda, were in fact other 'island universes' and universe gradually came to mean all the galaxies we can see.

The truth is we are can only see so far. With optics, we are pretty much at the theoretical limit, Our current best hope of 'seeing' further is gravitational waves and while we can speculate about what they might reveal, we won't know until the results come in.
ken wrote:Anyway, I like the definition 'ALL there is' for the term 'Universe', for if we do not use that word, then we will have to create another word, or just use the term 'ALL there is', itself, to replace what 'Universe' once meant previously.
Some people use the term multiverse and the ' many worlds' interpretation of quantum mechanics is fairly respectable.

Well, if you notice, I was using the definition of 'everything we can see'. The evidence that all began to exist is the red shift of galaxies.
ken wrote:If the only (good) evidence that the Universe started or began to exist is because human beings can not see prior to that bang with their eyes, then to Me that is NO evidence at all. That just shows Me what human beings, in this day and age, are able to see and thus how far they can see and look. That short-sightedness is NOT evidence.
It's absolutely true that we have no direct evidence of the conditions in which the big bang took place. But physics concerns itself primarily with what we can see. You can make up any story you like about the stuff we can't see.
ken wrote:Human knowledge predicts that every action causes a reaction.
Newton's third law of motion says that for every action, there is an equal and opposite reaction, but that's not the same thing. We have no knowledge of the behaviour of nothing, because we can't create nothing in the lab.
ken wrote:Obviously any size bang is a reaction from some other previous action, no matter how small or big the bang is, therefore the big bang was caused or created from some other thing.
"Obviously" is a bad way to start any argument about the nature of reality.
ken wrote:If EVERY action causes a reaction, and EVERY effect needs a cause, then this process, in the "end", would ultimately be infinite, would it not?
It's the IF which is big, rather then the every.
ken wrote:What is obvious to Me and what I see is IF every bang is caused by some thing, then even that one generally referred to as the big bang must have been caused by some thing.
It's a tenable hypothesis, but not one we can currently test.
ken wrote:uwot wrote:so there is evidence that the 'Universe' in that sense began to exist, but there is bugger all evidence for anything beyond what we can see, for the simple reason that we can't see it.
If there is bugger all evidence for anything beyond what can be seen, then what leads people to begin to assume that the Universe began? If human beings can not see past the big bang, then there would be NO evidence at all leading any one to assume that the Universe began, right? So why do so many people assume that the Universe began to exist?
You'd have to ask the people who think 'obviously' is a good place to start.
ken wrote:Is the main reason that so many people believe and assume that the Universe began to exist because throughout humans existence they have been telling eac other, with strong conviction, that the Universe began? Expressing it EITHER began from a big bang or from a God?
Short answer: yes.
ken wrote:Another theory is human beings tend to look at and see themselves in other things, there is a word for this "putting oneself into others" or "seeing oneself in others" but i can not think of that word now...
Anthropomorphism.
ken wrote:...anyway could of human beings believing themselves began to exist also then start believing ALL things must also begin to exist, including the Universe, Itself?
Some do.
ken wrote:If human beings can not see some thing, then why would they think it best to assume any thing? Would it not just be better to remain open till the facts are found? Then once the facts are found, thus seen and known, would that not be a better way to share the correct and right knowledge?
For all the crazy ideas people explore, ultimately that is how science operates.
ken wrote:Maybe if human beings looked from what they know is right instead of only looking from what they can see with their eyes, then they to would notice that If EVERY action causes a reaction and EVERY effect was caused then the Universe did not begin, with any kind of bang.
The moment people give up on their eyes, they stop doing science. It's that simple: if it makes no difference to what you can see, it isn't science.
ken wrote:For example I can see a human baby but I can not see before it "began" , that is I was not 'there', so I can not see from that advantage point. I can not see from that place of 'before,' where it came into being from, where it was caused or created, but we KNOW that a place existed before. Yet somehow when it comes to the the big bang for some people they want to just instantly assume that it inexplicably came from nothing, or came from an inexplicable God.
Now if we are going to say a human baby must of come from some where and/or it must have been caused or created from some thing, then why do some human beings not apply this principle to the big bang? Why do some people persist with the notion that the Universe came from nothing or from a God? Where is the evidence?
We are constantly in that place. As you read this, there are babies being conceived and born. The mechanics of that are reasonably well understood, but when that bundle of joy becomes a person, with rights, is a thorny issue. There is a broad spectrum of option, which in current western dialogue ranges from the potential, which prohibits the spilling of seed (Onanism, wanking to you and me. See ch. 38 Genesis for details. Long story short: God kills Onan for having a wank.), through a spermatozoa penetrating the cell wall of an ovum, to the fusing of nuclei, the division of cells, a whole number of stages in embryo development up until some shifting point that people who know tuck all about anything insist a foetus can survive outside a womb, all the way up to birth. Even then, personhood is still not uncontestested

I'm afraid I don't follow the logic.
