That's just what they've done in our lifetime. I hate to point this out, but keep an open mind as to what the original Bible may be like compared to what we currently have over many centuries. I know that's a tough one to think about being changed as so many have considered it their "Base Operating System", but it needs to be considered that there's cleanup in there as well. That having been said, I think it's safe to say that every civilization has reference to One Being that's responsible for creating everything. And I'm pretty sure He's pissed at what's been going on!
