Who is stealing my free will? Will they return it, please?

So, according to science, we have no free will. According to religion (sometimes) (sort of) we do. Do I have to pick a team? Can I pick neither?

See Radio Lab "Beyond Time" episode. Briefly, someone did an experiment wherein they asked people to wiggle their finger whenever they chose, and monitored their brian activity. They looked at two things: the decision (on the higher thought processes) to wiggle the finger, and the 'getting ready' or preparation to wiggle. Instead of seeing what you'd expect: first the decision, then the preparation, they saw the opposite: first the preparation, then the "decision." And they were like a second apart. So the people were preparing to wiggle, and THEN rationalizing it. And of course, the question becomes, WHO made the actual decision to wiggle the finger. Some part of the brain? God? Random forces of the universe? This freaks me out a little. Oh, and yeah, this wasn't so brief....
