Didn't anything happen before big bang?

"Big Crunch"

There was no "before" the Big Bang. Time only came into existence at the moment of the Big Bang.

Everybody got drunk but me. I'm still resentful I was not included.

That's my understanding, too. Actually, I don't understand a bit of it, but maybe I read it somewhere.

before the Big Bang which would be existence there was no thang. this is not something that can be comprehended in a way to where you can fully grasp the situation due to the fact that something only exists to us if we can observe it somehow through are five standard senses or are sixth sense but no thing cannot be observed because it's outside of our understanding this would be what Christians called God. so the Big Bang was basically an idea

We don't know if there was something before the big bang. We only have evidence from the bang forward. None for prior.

To be more specific... “Our” Spacetime came into existence at the BB. It’s possible there are other Spacetime bubbles outside of ours. But we have no data on that.

The producer and the production company had a preview screening of the new cosmos, catered, of course, for the cast and the media. Far too many people got drunk, and usually rude. That didn't affect the cast, because no one expects actors to have a lick of sense. Several people, however, from the production company were out of work the next morning.

There had to have been something because the earliest stage of the Big Bang commenced at about 10⁻⁴³ seconds, i.e. Planck time (tₚ). In other words, the universe came into existence when it already had an age of 10⁻⁴³. The problem is that we can't measure what came before because that is the time when the physical properties of the universe became viable. We're trapped within the universe's physical bounds, so to speak.
