I think it's more complicated than just saying fate doesn't exist - although if there is 'fate' there's no reason for any individual or being to be controlling it.
What manic_man said about everything being a series of events is definitely plausible. It depends completely on how you interpret the probability aspect of quantum mechanics though.
Disclaimer: This may be a complete mis-application of a principle but it's worth thinking about, however incredibly badly I can explain it. I know very little about physics
As the theory goes (general relativity when it boils down to it), just by moving relative to another object, you experience time differently to that object. You exist in the same 'time frame' as the other object did at a different moment in time. As you get further away from the object the effect is accentuated so that even moving at a low speed you exist at a time years in the past or future of the object. [Of course you never actually see the object in that state, as the light still has to travel the millions of light years to reach you.]
Extending this to the idea of fate, in a simplistic view someone just walking at a gentle pace on a distant planet has experienced every time frame of our entire lives and far beyond, as we have theirs. By jumping to conclusions

, this means that everything that has ever happened and will ever happen exists all the time, and there's nothing that's not predetermined.
There's a lot of big leaps in there which aren't all completely sound though, so I'm not saying that's the way it is... heh.
My rather vague information is from reading
The Fabric of the Cosmos a couple of years ago and I don't have my copy around
