Are you suggesting we not even try? What scientific progress would we ever make by thinking like that?

He never said we shouldn't investigate possibilities, but you shouldn't expect an answer.

For the OP, the rules of physics we currently understand are consistent for the energy and density of the universe as it is now. Working backwards they break down under conditions of high energy/density. Our nice predictive mathematics which work now don't at that point. It's been tried.

Let's suppose that there was "something" before Big Bang. We cannot say there wasn't or there was. What needs to exist is a means of examining conditions which cannot physically exist nor can be reproduced even in principle. Without the ability to study the initial conditions there is absolutely nothing that can be said about them beyond an arbitrary point. One might infer things, but to know? Nope.

So we're left with the puzzle of guessing what happened before.

I'll give you a problem that if you can solve then you will have found a way to answer the question of "what's before".

In this scenario you are the only person. There is no record of anyone ever having come before you, and no reason to believe another will just come after. At some point you just came into being and you have a memory of what's happened since the moment of your appearance.

Here is the challenge. Find a means by which you can remember what happened to you before you were born.

When you can tell me how that's done, then I'll tell you how we can access the record of the universe before it came to be.
