The free will thing is the biggest question for humans, and the most oblique and cloudy to understand. Maybe this has to do with quantum threads that live teetering on the edge of chaos. Just as a pseudo random number generator falls short of randomness, so does the typical view of free will fall short of accommodating our perception of how much of that (free will) we really have.
So, the idea that random choices that are not really random just look like free will, is an idea that falls far short of really explaining how the human choices we make are freely made. For now, the answer remains a secret. but perhaps the supernatural plays a part.
We are awash in connections (those being between quantum objects), yet with increasing distance between those quantum-endpoints, the interaction with the most far-flung of those objects decreases, such that we are mostly affected by our immediate surroundings and our inner selves (where both or all quantum endpoints are “homed” within ourselves, and only a few are extended).
This is forutunate, or we’d be composite beings with no self identity. If everything comes from the aether – even all the energy that is manifested as moving bumps within it, and if matter also is formulated as closed circular self-perpetuating bumps within that aether, then we can say for sure that the universe is made of a single elemental clay. God’s clay.
