If God created everything, wouldn't everything indicate the nature of that source? So what would make the Bible so special? Couldn't we learn about God from nature, art, politics, and everything else? The notion of "divine inspiration" is vague if it's supposed to amount to something more than that ability to learn about a cause from its effect.

Are you saying the other religions' scriptures are just as divinely inspired, or that they're similar to the Western religions in that politics got in the way of the inspiration?
