We experience the free will all our lives and your explanations don't explain this fact. Or at least they don't explain it in any reasonably simple sort of way. The irony here is that in this case the scientific approach leads us to a non-scientific conclusion, I.e. that there is such a thing as free will and it has an impact on the way this universe functions. "Look, I will to move my hand and now all these atoms are moving in a direction that I wanted them to move!"
If we go down to quantum physics then maybe we will find that at some point the will of an observer can change the outcome of a quantum experiment.
