The Explanatory System in the Brain

We find that people are more curious about the answers to questions about science than about religion. We seem to be much more comfortable with the idea that we can't know, and perhaps that we shouldn't know. If i ask you, why is rust red? And i say, it's a mystery, that just seems wrong. But if i say, why does god exist? It's a mystery. Why did jesus walk on water? It's a Mystery. What do you think this reveals about the explanatory system in the brain?...
