We might be a bag of chemicals, but chemical reactions obey Heisenberg uncertainy principle. I mean, you cannot predict the behaviour of a bacteria in the far future just like you cannot predict the behaviour of anything in the far future because we don't know with infinite precision the position and velocity of anything.
In the end we don't know if free will exists because we just don't know the inner works of the tiniest particles.
Listen, I try to be reasonable with you. I read what you write and answer accordingly, providing scientific papers that you can check and read.
However, if you keep writing whatever you believe without ever checking the scientific literature, you will never learn anything new, and the discussion will never move forward. If you don't have access to the papers, you can always check in your local library or university and download them for free.
I know it's easier to just read the first 5 lines of a post or keep repeating over and over like a broken record what you might have have studies at college for an exam or two, but if you want to argue about something you need to have an open mind, read the scientific literature and check it for yourself.
