Although we can interpret the currently very popular Life of Pi (the book or the movie) in a variety of ways, one thing that we might take away from it is that if we are to believe in God at all, we must accept something that, given earthly sensibilities and common logic, we might not necessarily be inclined to accept.
     But perhaps that's the point.  We will not believe in God unless we are willing to believe that, as philosopher Ludwig Wittgenstein wrote in his Tractatus, "The facts of the world are not the end of the matter."
     Or as the poet Emily Dickinson observed, "This world is not conclusion."  We have to believe that this life cannot possibly be without something (or, better, someone) else being there first.
     No one can produce herself.
