Why are we here, alive, apparently, but all dying? No one sent us unless we mean that we are the effect of a cause, an effect of countless causes and perhaps a certain degree of chance. They sent us in a way to where we find ourselves, and it is our life experience, all the effects to our lives, that guide us to what we want to do in life, although most of us never get that chance because of other causes and effects. By the way, this is one of the minor proofs of no free will.
We can always take a right when we want to take a left, but we will eventually take the direction that we wanted, unless both ways get us to a similar place. Free will would have been a disaster had it been real given the history of human cruelty and heartlessness. Remember what we have done without free will. Now, imagine what would have happened if we had free will. This is a second minor proof.
We can even reverse it. Remember what we have committed with free will. Now, imagine what would have happened if we did not have free will. It is not easy to even just pick one that we like, since the scientific data is stacked against free will. Now, does it even matter whether we have free will or we do not? We live in this reality and we have no choice in the matter. We were sent here.
But I will add that I may be wrong. Almost nothing is 100%, and this free will so-called issue can still be studied. Someone can always find a way to show that there is free will, or that there is no free will. But again, which one is really better?
