Obviously, we're not mindless automatons
For example, as you pointed out, we do have self-awareness. Although, in one particular sense, we are still like automatons: Whatever we do, we could not have acted differently. Given the laws of nature, the current and previous physical states of the universe, whatever happens next is
entirely determined. And while the future is (thankfully!) much too complex to predict, it is still
determined in the manner I explained. (This view is called physical determinism.)
(And before you interject "but quantum mechanics!": I'm telling you those people are misguided! There is a difference between apparent randomness and true randomness. In Einstein's words,
God doesn't play dice with the universe! And even if Einstein is wrong and quanta do behave somewhat randomly, how does randomness help the case for free will!? Free will is stuck between a rock and a hard place, between determinism on the one hand and indeterminism on the other.)
