It's essentially the question of free will.

There is a case that everything we do is preordained. A result of forces and interactions that trace all the way back to big bang.

My choice on whether or not I reply to you doesn't exist. Your combination of words triggers a response in my brain that makes me type this combination of words. The words I "chose" to delete, rewrite, leave, are all a result of various forces.

The kicker is that we can't really know. There is no test for free will. In order to know whether or not I had a choice to do this, we'd have to run the entire universe again up to that point to see what I would do. Because experience matters. Even if this exact same post went up tomorrow with all the same response except for mine. The fact that it's now Thursday instead of Wednesday matters. The fact that I posted this today matters. What I had for lunch. How fast I drank my coffee. What shirt I wore. Etc. These are all things that change the conditions under which I will engage with the post.

The second kicker is that it doesn't matter. If free will truly does not exist, it's not like you have a choice in whether or not to believe in it. The arguments either will work or they won't.
