You get the exact same effect when you wave your hand back in forth in front of your face really fast. Even you, the person waving your hand, cannot tell where your hand is! It looks as if your hand is in multiple places at once! OMG, does this mean there are two universes where my hand is in the right side of its motion, and another universe where the hand is on the left side of the motion? Hell no! The problem is one of perception. We can't sense things at that speed. And even with our best science and equipment, we cannot tell where the particles are...so what? This means our science and equipment are not good enough to tell where they are, not that they are in multiple places at once. allot of these guys need a healthy dose of common sense and maybe, a basic course in philosophy.
Those electrons are precisely where they are, in according to laws which they follow. It does not matter that we cannot see them or that the laws are far too complex for us humans to understand. Its gods laws, and if we can't understand them, thats on us. Instead of pulling ridiculous theories out of our own pretentious @ssholes, why cant we just accept the fact that we dont know and might not for a long time, if ever? Its just more people thinking they're god and that they can understand everything. Instead of admitting that we are limitited in our understanding, we start making **** up to make things make sense. This is the exact same thing people have been doing since time immemorial.
But how does that prove that you did not freely choose the choice you did? Free Will doesn't mean that you could have chosen differently than what you did. I think it means that you freely chose what you did. It was an act of will on your part as opposed to simply causation derived from chemicals and atoms and synapses in your brain. Without free will, choice is simply causation compelling you. With Free will, the self chooses what it chooses.
This isn't to say causation doesn't have a strong role in that respect. Humans are animals and spirits, so it makes sense that our choice is both causation and free will. If not for the fact that humans choose evil, we could easily say that Human behavior and choice is simply animal choice that is very complex. But Humans are clearly capable of a type of morale choice which does not appear at all in the lower animals. At best, there are very, very rudimentary behaviors which resemble (but are not!) our own morale choice ability in higher mammals like Apes.
