I am astonished that no one has mentioned the weak and strong anthropic principles throughout all of this.
http://en.wikipedia.org/wiki/Anthropic_principle
The strong anthropic principle says that the universe is as we observe because it *had* to be that way ... this is sort of a non-theistic version of the fine-tuning argument. There seems to always be the implication that the universe was created for the purpose of allowing sentient life to evolve, but the question of an intelligent and willful creator is often side-stepped. The SAP is *consistent* with the universe having been deliberately created for "us", but that is not required. One of the interesting variants is tied into the Conciousness Causes Collapse interpretation of quantum mechanics, and basically says that the existence of intelligent life *now* has interfered with the quantum state of the universe (in the Feynman sum-over-histories sense) all the way back to the Big Bang. That "interference" coalesced the universe into it's current form, where sentient life exists. Personally I think it is all just metaphysics .. but it is fun to think about.
The weak anthropic principle is more favored by scientists in general (I believe Hawking is an adherent) ... it says that we observe the universe as it is, because if it were significantly different, then we wouldn't be here to observe it. Thus our position as observers is necessarily privileged. The WAP is also consistent with deliberate creation, but also admits other possibilities, like the "trillions of possible universes, but we only happen to be in just this one" raised by JaredJames. I personally favor this interpretation, because it seems to take less for granted, and allow for more possibilities ... however it is all still just metaphysics until someone can figure out an experimentally falsifiable hypothesis that let's us distinguish the difference.
Anyway, there is an absolutely great sci-fi novel related to all of this by Neal Stephenson .. it is called Anathem. It would be cool if things turned out the way they are in the book ...
[EDIT: whoops .. kinda got lost writing that .. anyway .. my point was that vjk2 seems to be arguing the SAP, while ryan and JaredJames are arguing the WAP. I thought maybe introducing those terms might help the conversation break out of the loop that it currently seems to be stuck in.]
