Prove that free will doesn't exist?

Question

When some scientists say that free will is just an illusion caused by the neurons in your brain, then "who" is there to witness that illusion? I mean, isn't saying that we have no free will more like a philosphy than real science? Until you can prove that you have no free will, making a claim like that is pretty irresponcible, because people assume that scientists know wat they are talking about. Its like if you said the universe is a n illusion, wll it might be, but iff you can't prove it, its not science, it requires as much faith as any other faith, agree or not?

I guess you could say "prive free will exists", but you don't have to. If you are going to make a claim that contradicts everyday experience, your the one who has to prove it

please be civil

Answer 1

Im choosing not to give you a good answer. I think my free will is working pretty well.  

Answer 2

My free will demands that you DO PROVE FREE WILL EXISTS

Oops, I think I just proved that for you.

Answer 3

Our free will extends as far as our brainwashing will allow. That isn't very far for most people. But the brainwashing includes believing that we actually make our own choices. Sure, out of the few that are given to us.
