Rationally speaking, how could a creator of the entire universe and everything in it be encapsulated in the modest human capacities for understanding? Such things as the Bible, or, indeed, anything that tried to discuss such a deity could only ever do so in the most roundabout fashion. Metaphor would be the most we could hope to achieve. It is an insult, in fact, to "God" to express even the possibility of reduction to human language. Pointing to truth is all we are able to do; defining it is ridiculous at best, blasphemy at worst. Naturally, if one does not even believe in such a creator, religious texts are merely tomes dealing with regulation of society.
