To my knowledge, we also have zero evidence that they didn't exist. Nor have we ever observed matter/energy appearing out of ~~thin air~~ vaccuum, so it seems unlikely to me.

And to my knowledge there can't be a before time.
Oh yeah? Then where did they film The Land Before Time? Checkmat
I like how there are at least three things that are immediately recognizable as wrong with this question.
Well, everyone has a skill I guess

Can time really exist if there was no frame of reference to measure it? We can only detect it by motion or entropy. It's the only way of "time". So if there was some point where there was nothing that moved, then time wouldn't exist.
For that matter, there's no way of measuring if time is even consistent. If it were constantly speeding way up, or slowing way down, we'd have no way of knowing.
Time is just a figment of our imagination so we can keep track of movement. Just like magenta isn't a real color.

Well, yes and no. Time is a concept derived from a change in state. There is no “real” time. If the universe before the Big Bang existed in a static state, then the concept of time itself becomes meaningless. So in that case, it would be “before time” in a sense
The state cannot have been absolutely static - if it was, the big bang would not have occurred, and the same stasis would be existing now, unchanged.
Duh, spacetime is a casual filter.

Well, we haven't directly observed matter appearing spontaneously in a vacuum, but we have evidence to support it does happen
“Before” the Big Bang is nonsense. It’s equivalent to saying “head north from the North Pole.”
It's not so much that we know there was nothing before it, but that we can't figure out what was before it.
No, in our current best-supported model of the universe (Lambda-CDM) the concept of “before” the Big Bang is meaningless. It is the apex of the spacetime “bell” from which everything emerged.
But something must have triggered the big bang. The model might not support this, but this only means the model is insufficient to describe what goes beyond our known universe.
But something must have triggered the big bang.
That's a separate claim you'd have to prove. We have no evidence of something triggering it, we don't even know that it would need to be triggered. All of our observations occur inside this universe, therefore we have no idea at all if cause-and-effect even applies to the universe as a whole. The short answer is: we don't know and have no reason to posit the need for something else.
What does it mean for something to be "beyond" everywhere or before time?
I wish we could see beyond our universe, I want to know so much.

very nice analogy. I'm stealing it.
That's nonsense. You think some massive amount of matter just materialized from nothing into a singular point? How do you think all the stuff managed to get there in the first place?
Not just matter but time as well. That's what they were referring to. There is no "before time".
Regarding your rethorical question: go find an answer and you're sure to win the Nobel Prize.

It's only something we can speculate about. It represents a limit to our ability to gather any evidence that might validate those speculations. We can't say what happened before it, because time itself was one of the things that popped out of the big bang. What would "before" even mean if time didn't exist?
Even if time and matter did exist in some sense, we can't get any evidence for it. We can't make any kind of useful theory about it. At best, we can make wild guesses.
We could also just say "we don't know what it was like". Russell's Teapot suggests we should instead say there was nothing, because we can't prove there was anything.

It wasn't matter that did the banging, it was space-time itself. Have you heard how we know that the universe is expanding? Well we can extrapolate backwards and find the point in time where space-time was just a point: "the big bang". Not only was there no space-time for matter to exist in before the big bang, there was no concept of "before" because that word only makes sense in the context of spacetime. So yeah, the person you're replying to is right, "before the big bang" is a nonsense phrase.

Based on the comment you're replying to, I assume they would say "no, nothing materialized from nothing because there wasn't a 'before' in which nothing could have existed"

Evidence of god?
ZEROOOOO
I know it's old, but I still cannot believe it's the same woman in every panel. Girl looks like a different person in each pic.
The original commercial was showing different women as if to imply it works for anyone. The arrangement of the panels is different from the original ad. It looks like panels 2 and 4 are swapped. I believe there are 2 different women.
If you look at the straps on her outfit,it looks like it's two people.
That's what I was thinking. And I just noticed that in 2 of the pics the shoulder strap to her shirt is different. If it's not different women, it's at least different shirts in some of the panels
It's not the same woman. It's an interview style advertisement with 2 women. Here's the ad - https://youtu.be/1n9sLzlxPf0?si=GFUfdfBUpA5BFazE
Hey, man, we're all just echoes of light bouncing around and making good vibrations as we bounce pgf of each other. Yeah, man, like, totally trippy when you think about it.
I think the inability to destroy or create matter counts as Evidence but not necesarily Proof.
It doesn't as the laws of physics as we currently know them break down at the scale and pressures involved in the very early universe.

Well, the equations that predict black holes also predict white holes, and the big bang is functionally equivalent to a white hole. And we have found black holes. So...seems like the most plausible explanation for the big bang is...it was a white hole. Still can't extrapolate backwards for the same reasons, but there are at least implicit causes of white holes suggesting there was spacetime before the big bang.
Those cosmologists would be very upset if they could read.
Well you're forgetting about the big unbang, which occurred just before the big bang and condensed all matter and energy into a tiny speck.
