Granted your initial assumptions, I agree. Of course, as you can probably tell by my other posts on this thread, I don't share your assumptions, and therefore can't agree with your conclusion. =]
To me it's like 3 people who think there's a giant pink bunny on the far side of the moon that controls the world.
One guy calls him Stan, and he's a good bunny that's responsible for the good things of the world and if you're a good person, you'll live with him when you die.
Another guy calls him Stan too, but the bunny is fairly cruel and demands you to believe in him, or else you go someplace away from the bunny when you die.
A third guy believes in a pink bunny, but calls him Robert. Robert the bunny will offer you a planet of your own to watch over when you die.
I'm making analogies here of course to world religions.. It's all based on different interpretations of different fairy tales.
