Well, let's just say that the Big Bang (or better: the materialization process) is intact.

Yet, quantum fluctuations is just one option to fill in Option #3. The quantum fluctuation had to be present in potential, which means there had to be a reality that could produce that quantum fluctuation.

We can make that prior condition as small as we possibly can, but we can't make it zero.

Also, we have to have a reason why that quantum fluctuation started to occur. That is another reason it could not have been zero.

We need a breakage in the setup before we can get an outcome that is distinct from the prior reality. If it was not a breakage, but rather a natural development, then a return to the original state would have happened soon after (and not endured for 13.8 billion years).

We are stuck with two realities therefore, and we exist in the second reality. The prior reality (whatever it was) had to undergo something dramatically otherwise there would not have been a result.

For sure, option #1 does not really exist. I had to mention it because some people like it and the brain can conjure it. Again, it is structurally not available for the train cannot leave that station.

Option #2 is in my view not that complete either, but I'll mention the eternal universe as potential in this category. That means the universe is eternal and we are then not living in a result, but still just in the original. Not a fan of it, but it can be mentioned.

Nevertheless, I hope you see how that option does not provide us any good handles on the current state.
