Inverted Inevitability

Is everything inevitable?

My theorised tentative conclusion was that, if consciousness is a precise predictable calculation, then all conscious decisions (along with all occurrences in the universe) are likely inevitable to pertain exactly as they do. If this was so, everything would be 100% pre-determined, and it would be impossible to change the outcome of what is going to occur.

This initially seems contradictory to there being any potential purpose to anything occurring, as it would indicate that a conscious entity causing an intentional action, will create no different effect on the inevitable outcome. Everyone would be bound to make every single decision of their life exactly as they do.

Digging deeper, maybe it is possible that there is a purpose to existence, despite its inevitability. Perhaps all plausible decisions in the lives of every decision capable entity to ever have lived, and which will ever live, are absolutely determined at this point, and the point they occur, and at every point in time, except the instant which the universe began. Before (taking that term lightly) the universe began, when (also, lightly…) time was at a stand still, maybe at that moment (diddo) there was varying plausible outcomes to the universe, and every action and reaction within it. Perhaps in that instance, all decisions ever to pertain, made a relevant difference with their uncertainty and indefinite potential.

All decisions -as well as of course all unconscious, physical reactions of all material in the universe, ever- would then be predetermined to an exact science and mathematical calculation, from that point on, of the universe spawning into existence, and time ticking its initial millisecond (or infinite division of a millisecond...). But, if before that instance, all occurrences were allowed the liberty of uncertainty and plausible alterations, then decisions could theoretically make a difference. With decisions having the potential to have a relevant impact on the outcome of the choice being made, this could allow for potential purpose to life, and the universe in itself.

So in theory, any decision you make, may be inevitable at this point in time, but it still makes a difference, as it was not inevitable at one point. Its almost as if, you making a certain decision, dictates how every molecule and atom in the universe was arranged as it permeated into existence. In the scenario where you were to make a different decision than actually occurs, the molecules would have been arranged differently, in some miniscule way, as the universe began, as well as every molecules’ interaction throughout all of history, which was connected to the chain of reaction to allow the perfect circumstances for you to make that precise decision.

The liberty of allowance, prior to the universe's procurement, of what is to occur in the future, could theoretically be what enables the plausibility of alternate outcomes of the universe, and consecutively, every decision you make.
