If we did not have free will, it would be impossible to predict ANY future events*. This is absurd. Therefore, we have free will.
I think the problem most people have with determinism is the scale on which it is played out. Yes, you can 'choose' between door one and door two. But take a step back and look at what led to that decision. Now take another step back, and another, and another, etc...........
The events that you speak of are future events only because we haven't conciously experienced them yet. In classical physics everything is determined. That has been improved upon,... in special relativity for anything moving at the speed of light time is non-existent, everything just is. Then comes quantum mechanics. In QM you can substitute classic particle trajectories with wavefunctions, and the same deterministic principle holds. The one hope that free will has (as far as physics is concerned) is whether or not human observation has something to do with a quantum wavefunction collapsing into an observable state. I suppose this is possible but I am not going to leap at it just because I want free will to exist (which I do).
Anyway if you are going to talk about events and our influence over them, you might want to look at the bigger picture. It may seem that you have control over the outcomes of certain events, but the only event that matters (the universe) seems to be indifferent to what you or I think.
