Most children at some time in their lives ask where they were before they were born, and who they would have been had their parents not met. However, they never receive any satisfactory answer and usually forget about it. So how about you? Have you forgotten? Well, if you read this and think about it, you will finally understand. If not, don't worry, it will make no difference to the reality of it anyway.
Let me explain the basis of understanding it. Suppose you take a nice sturdy bottle of champagne, draw the cork and empty the bottle appropriately. Now imagine that you can replace the cork and through it extract all the air and any stray electrons and pions and muons and quarks and such, and just suppose you could prevent any neutrinos from entering, then what would you have in the bottle?
Super. Congratulations to all of you who said 'Nothing', and you can each award yourself the Nobel Prize for Normality and elevate yourself on your shoulders if you wish. But look again. Manifestly the bottle still contains something. It contains space. Space it not nothing. Space is a structure, without which there would be no dimension. And look: there is a lot of dimension.
Space is the single ingredient of the entire Universe. Concentrations in space form the sub-atomic particles, which we can observe combine to form atoms of varying mass and stability, which interact with others to form molecules, living or inert. This matter also gives rise to the various binding and repulsive energies and, in quantity, the forces of gravity and, over vast distances, space-entension. Remote galaxies, static within their local space receding from us, are thus apparently carried away ever faster, but it is all done in and by means of this single ingredient of space, which, you might admit, is neat. You see, Universe, being an absolute, is absolutely simple.
However, though that is what we observe, we cannot see Universe as it really is. Being limited living creatures, chemical organisms that require atomic action to enable us to see and think and realise, restricts us to seeing Universe only moving and 'in action'. Say 'Now and now and now,' and each 'now' is about twenty miles farther along our orbit around the sun, plus a regular leap around our local galaxy, besides who knows what away from yonder remote galaxies. We call this impression 'time', but the reality is that timeless Universe is both static and already complete, and our bubble of perception merely flits and skitters through a very little of its local extent, observing it all as active.
So Universe is very different from what we experience. What we call 'chaos' in reality is the explicit and tidy order of what Universe has to be. And what we living creatures view as 'past, present and future' all coexists simultaneously. The microbial progenitors of dinosaurs are still alive 'there', as are the things of 'the future', but we and our fleeting bubbles of consciousness are locally and apparently transitorily only 'here', rather than 'there' to see them, or omnipresent to see the rest of it that already exists in totality. What and who you experience while alive depends on your mutual proximity in the locality in which you find yourself to be.
In passing, I will also mention that, in already complete Universe, every infinitesimal particle and its resulting inevitable inclusion on the vastest scale being involuntary, Universe therefore has to be as it is, and if you could run it through a zillion times, it would have no option than to occur in exactly the identical way every time. We being merely a part of the whole, if this happens to make us, too, fundamentally involuntary, well it is only our limited mental capacity that is persuaded to believe otherwise, and you can't blame me or anyone else for that.
Then where were you before you were born? - Why, here, of course, in Universe, but not 'yet' reduced to be alive as a mewling infant. And when your chemical activity stops and you are what any still living will then call 'dead', well, your remains will still be 'here', where your bubble of consciousness is now active, and you in whatever form will still be in Universe, as there is nowhere else for you to be, though exactly where you will be present and in what precise form is a bit imponderable. There is evidence of a continued purely-spiritual existence, but few of us can envisage that. Similarly, whether 'before' you are born you can already exist as a spiritual entity with experience of life is hard to say, though in the singularity of Universe it seems reasonable. However, in any event you will have to be here in Universe as, again, there is nowhere else for your materials, physical or spiritual, to be.
So do you understand now? - Well, if not, don't worry; it will be clearer in time, either as this information is processed by your brain, or in 'the future' when your chemical activity ceases, and you find yourself in the total generality of 'here'. In any case, good luck.
And who would you have been if your parents had never met? Oh, there was never any possibility that they would not meet, because they did, resulting in you. Things such as possibility and probability are only the mental concepts of an evolving anthropoid, sharing equal authenticity with the fictional 'value' of the fraudulent mirage of finance. They equally have no place in the real world.
Happier now? Well, no matter, but perhaps it is better for you to have had even so meagre a glimpse of reality, rather than being afflicted with only the 'normality' of the parasitic financiers and their obedient bribed monarchs, presidents and riff-raff 'politicians', in which we in all our waking moments are saturated, and by which they have enlisted our mindless acceptance of their predations.
Time to wake from our artfully-induced slumber? - You betcha.
