Neuroscience and God

Neuroscientists have been able to track down sections of the brain that light up when nuns recall epiphanous moments. So what does this mean about God and our relationship with God? Not being a neuroscientist, it doesn't mean a whole lot to me, but be certain that people will use it an excuse to argue about the existence of God.

Just because the brain lights up in reproducible ways when a person is thinking about God doesn't mean God is a figment of their imagination. It's like saying that litmus paper changes colors when I drop lemon juice on it because the paper really likes acids.

I'll stop now... it's early and I need coffee. What do you think about all of this?
