My two bits. In thinking about before the big bang I realized there are some things we might never know and am content to leave it that way.

I am more happy to think that someday someone will have an insight which is a reasonable explanation for it all. It won’t be testable, obviously, but humankind is always grasping for an explanation - else we would all still be worshiping Ra the Sun God or whatever other superstitious nonsense someone dreamed up.

For a long while nobody could explain how animals came to be in such variation, or what possible mechanism could account for the proliferation of predators and prey, the similarities but differences, and so on. Then one day Darwin came up with a hypothesis which made so much sense it blew the myths out of the water.

No one understood how atoms were held together, or what the relationship was between space and time (or if there was a relationship at all) and then suddenly Einstein. Likewise disease and antibiotics, and a hundred other steps humankind has made in this long journey of ours.

I am hopeful, pretty confident, actually, that at some point in the far distant future (assuming we get there, of course) there will be some hypothesis proposed which will explain in understandable and believable detail what happened “before” (acknowledging that there is no “before”) and how all of this we see and touch and feel came into being.

Until then, “I don’t know” is sufficient for me.
