What was before the big bang.

Not in the way they are saying it happened. Space is something like a substance that is part of universe. It was created at the moment of the big band and is expanding, but nothing exists beyond it.
Another point of interest, everything we see in the universe makes up ~5% of what is there. ~24% is dark matter which exerts gravitation force or galaxies would fly apart, but we have no idea what it is made of. Rest of universe is dark energy which is causing expansion, but again no idea what it is. So universe came from nowhere and we only know what 5% of it is, and no idea why the forces of nature, gravity, strong nuclear force are what they are?
E=mc(squared) implies that matter can be created from energy. It's not a one way street.

What was before the Big Bang? If there was no space or time during that moment, how did everything suddenly appear out of nowhere in an instant?
The Big Bang did not emerge from nothing but from singularity that encompasses everything within a density such that it equals zero. We have not yet discovered the precise how, but we have observed the effects.
The observations of the Hubble and JWST have provided extensive data as to the early origins of the universe which continue to challenge what we think we know and thought we knew.

Scientists have been able to recover a sound from two seconds before the Big Bang.
When they played it back, it was: "Uh-oh".
I'd heard it was "Honey, hold my beer while I light this."

So much we don't know... There is not even consensus on how a signal propagates along a conductor. Schools still teach that electrons flow like water in a pipe.... Even B. Franklin had it wrong about current direction; hence conventional current and electron current. You think the Canonite Nikonite battles are bad here, go on an audio site and start discussing high end cables and signal propagation... Ha Ha
Ben Franklin did not know the direction current flowed because he had no instrument to tell him and he had to guess. He did guess wrong. I was taught that AC current flows through the wire like water in a pipe and DC current travels through wire only on the surface of the wire. That is why household wire (Romex) is single stranded and automotive wire is multi stranded. The information may have changed and I would be open to knowing.

I hear you... Yes, to the best of our knowledge current does flow, but NOT electrons as books still teach... They might wobble and move a little but the charges are the things that flow... I belong to a lot of audio forums and do not profess to be any authority on electronics but it seems there is STILL no consensus on how a signal propagates along an audio cable... Through the center, on the exterior, or maybe along the magnetic field... Therefore we have our own constant flame wars between the different custom cable manufactures as WHY their designs transmit with less distortion Etc... BTW, very interesting info on DC and AC and how they travel... A little exchange of info is nice without folks resorting to insults etc... BTW, I DID buy into Upper end cable and I DID notice a difference... subtle, but noticeable. Maybe just the " Expectation effect " but then again who cares as long as it is REAL to you...

Just undiscovered country.
This is a dark matter universe...what we consider to be the universe...is but a film of elements lying in a vast ocean of dark matter...insignificant statistically to the universe...an afterthought...side effect.
We are the first generations of mankind to understand...something.
We are observers...not participants.
We are the first to actually know that as a culture...
Be glad...at least you know.
None of your ancestors knew...the information simply wasn't obtainable.
No free will...but you get to at least observe something with clarity.
It's a first.

Just what makes you so sure we were the first of anything?

I believe our universe is just like an atom in an even larger universe
