wondrous equipment that allowed them to detect religious belief, to give us a kind of heat map of faith, this is what our planet would look like.

Personally, I am not religious in any conventional sense, but I do consider myself spiritual and I certainly do consider myself curious. One thing that I have certainly gotten ever more curious about is why do we believe?
