AB,
By dismantling, I assume you refer to the alternative arguments…
Then you assume wrongly. By “dismantling” I mean the invalidating of your arguments whenever they are logically fallacious. A bad argument is a bad argument, no matter how sincerely you happen to believe in its conclusion.
… that we came into existence by the product of random forces acting within a big cloud of gas…
Depends what you mean by “random”, but if you mean something like “purposeless” then yes.
And “we” came into existence a long, long, long time after the “cloud of gas” – all that was necessary was the starter conditions that eventually led to organic chemistry, that eventually led to single-cell life, that eventually led etc etc
assisted by a crude filtering system based on survival.
What “crude filtering system based on survival” are you thinking of? If you mean evolution, then it’s actually a remarkably elegant and powerful mechanism for speciation.
And the assumption that science will eventually define how awareness works…
Straw man. What we know is that “science” is the only method we have that reliably and verifiably models reality, and it seems reasonable therefore to think that it’s our best bet eventually to “define how awareness works”. Whether it will ever do that however is at this time unknowable.
…and that free will must be an illusion because it can never be explained in physical terms.
No, free will as you define it is almost certainly illusory because that’s what the evidence indicates, and moreover you have no definition, no method, no
anything to test your alternative conjecture.
