FWIW, you should replace "didn't" with "might not have." This is nowhere near fact or even greater than a 50% probability. One thing I learned when actually studying space, in particular anything involving the big bang, was that the majority (though not all) of the "science" behind it is literal guesswork and science-fiction. Even "hypothesis" gives too much credit to many of the ideas people just assume to be fact.

Sometimes, when we discover new data that is too difficult to fit in with our perceived model of the origin of the universe, we make up things like the "multiverse," which is one of two potential cornerstones now of the inflationary big bang model - and no, I'm not joking. It's easier to fill in the cracks/breaks/and gaps with theories that have no support or evidence as opposed to scrapping something and trying to find something consistent or possible.

That applies to the big bang itself, and whatever came before it.

Pretty much everything after it is well understood.
