If people who believe in a magical bearded sky father manifesting their bedtime wishes and helping devotees win sporting events and awards are somehow taken seriously, well, I feel perfectly fine choosing to believe in free will.
Humanity didn’t have a clue about all kinds of shit just a few generations ago. It’s quite possible that there is more to the world than what we currently understand and that we really are more than some crazy elaborate finite automata. It’s an egotistical blindspot to think that there are no more unknown unknowns.
