Do you believe in free will? Why, or why not?

I see some posts mention it and a lot agree it does exist, and then another where the comments agree it does not. This isn't to see how many agrees with each "side", just to see why you think what you think :) (You can just believe whichever without a reason behind it which is fine too)

My answer is I believe in it. Saw someone else mention they don't believe you can control your wants but you can control your response which i agree with. Always thought you have set traits that aren't controllable such as likes and dislikes or humor or wants etc, they can be influenced by new information or extra thought, but not just straight up changed intentionally by yourself because you felt like it. You can, however, control your actions and your thoughts. (Also I don't get "your thoughts are not you" I've already had that panic attack lol. If my thoughts are not my own, neither my actions, who am I then and what have I done after existing for potentially longer than I've been alive? If my existence is not my own then how come I experience it?)
