Why is this thread still going on?!?!
It's what threads do. If they're good at it, they can keep doing it. But there's always people wanting them to stop. These people are quite selfish, I must say.
Interestingly, something made me wonder what it would be like if I swapped "thread" with "religion" in the above conversation. And it seems to work. Although I would expect the hard-nosed evangelist atheists to complain about being called selfish, and the ultra-dedicated religious types to complain that it isn't taking their POV seriously, and just trying to show that it's a 'mere' meme.
But that comment is just a segue to a basic analogy that occured to me last night...
You're sitting on a picnic blanket, in a field, and looking up... Hey! What's that travelling across your vision? Maybe a fisbee (actually, it was a paper aeroplane, originally, but someone else mentioned a frisbee in another context, and that works better)... in which case it's an indication that there's an intelligent person out there, off the edge of your line-of-site but obviously there in some form or another, who not only made(/purchased) the frisbee (or paper aeroplane) but launched it across your vision. Or maybe it's a cloud. A natural phenomena which has rational explanation behind it, even though you're not in a position to go and take high-altitude humidity, temperature and pressure and airflow readings, or to establish their exact conditions back as far as the cloud's original appearance. It might even be a bird. A living being, with its own (albeit basic, and probably far less philosphical in nature than you are) intelligence and drives and motivations and intentions.
And that's equivalent to three (of probably far more) visions of what we think the world we know is about (and/or the observable universe in general), given our limited perspective in both viewpoint and period of time that we're observing it. Somebody's creation, a natural occurance of no extraordinary nature and (maybe) some sort of Gaian hypothesis where a hyperconsciousness exists among the complex interactions of so many simple systems. You probably have your own objects in the sky/philosophical worldview equivalences in mind, for your own or others' opinions about the nature of things.
Of course, as a person having a picnic, we would already know about frisbees, birds, clouds, etc, having seen these things before and learned at least some of the details about their origins at a time when not lazily reclining on the ground after too many cheese sandwiches. As observers of the universe, we don't have that privilidge, which is why we're all having to work out what we think it is that we're seeing, and having to deal with contrary opinions from others.
