where those sorts of god questions come up more often.  I teach at a university, and the questions tend to be much more focused on IDC (I'm in Kansas, after all).  In a university classroom I can get away with just showing them why IDC is not science, and the students are pretty much able to grasp my point.

Had I a bunch of little kids, then I would entertain their wonder and talk about different ways that different people have grappled with those big, deep questions throughout the ages.  I would in no way try to squash the wonder about things (that happens too much and kills curiousity dead), but I would show them what we know from science and talk to them about how those deeper, beyond-science questions have been answered by different peoples.

You can respect their questions and beliefs without calling those beliefs "science," which is what the IDCers want to do.  Religion represents a different way to look at the world than science.  Science is good for knowing about how the natural world works.  In fact, it's very good for that.
