It appears to me that what she is saying is that some people believe what they believe regardless of evidence, one way or the other. As she has already stated, she doesn't believe because she doesn't see any evidence to believe in.
Who knows, maybe a few years down the line, new evidence is unvieled to prove that God actually exists, but I very much doubt that will satisfy, because if we find an existing God, it loses it's mystique and we then start the search for it's God as well...
Thanks for the great responses!
About something you said the other day (too far back to go find it now), while I appreciate the joys of fence sitting, and while I agree that both sides are flawed, I don't agree that they are equally flawed.
On the atheist side of the fence, the flaw is that you have to accept not knowing, you have to be comfortable with the mystery of the thing. But in return there is always the comfort of knowing that there is a possibility that the origin of the universe will be explained someday, and that when that day comes, the explanation will be good and plausible. In the mean time, you get to live a perfectly satisfactory life, with whatever priorities you choose.
On the believer side of the fence, the flaw is that is that the idea of an all powerful god/creator is simply implausible. While the concept of god can be conveniently used to explain pretty much anything you want (after all, he is not around to contradict you), you are still left with the question of where did god come from? Of course, you are left with many other questions too, like why did god abandon us, if god cares about us, why doesn't he intervene before catastrophe strikes, if god cares so much about whether we believe in him, then why doesn't he show his face, etc, etc.
I find that it is an uncomfortable feeling when I think about the vastness and complexity of the universe, and how I have no idea how it all started or where it came from. But I find it even more uncomfortable to think of some god that apparently created himself and then everything else with the snap of his fingers, and then dissappeared never to be heard from again.
