Sorry. Still trying to get used to this message board format. Ignore the previous post....
It's amazing how these "Does God exist"-type threads so often follow the same pattern.
"Why don't you believe in God?"
"Lack of evidence."
"There's all sorts of evidence."
"Where?"
"All around you."
"Be more specific."
"Ummm.....things just don't happen on their own, do they? So God exists!"
"That's not at all convincing."
Theist then proceeds to post bald assertion after bald assertion about what God is, how it operates, and how things work after you die...all of course without a shred of supporting evidence.
Non-believers are of course, unconvinced and say so.
Theist answers, "Well then, nothing will convince you. You're just too egotistical."
If I've seen it once, I've seen it a thousand times. Now, S-U suggest using logic to determine if a god or gods exist. Ok, let's do that....
--Many people assert the existence of a god or gods. Most claim direct revelation from this/these god(s).
--Virtually none of these revelations agree with each other, and the vast majority are mutally exclusive. Therefore:
a) God exists and communicates with humans, but does not communicate at all clearly, or
b) God exists and communicates with humans, but humans are terrible at understanding, captureing, and relaying these communications, or
c) God exists and communicates with humans, but gives conflicting messages to different people, or
d) God exists and doesn't communicate with humans, and humans simply make up/imagine these revelations, or
e) God doesn't exist, and humans simply make up/imagine these revelations.
Logically, if any one of these are true the first thing we must conclude is that we cannot rely on humans to tell us what God is, what it wants, how it operates, or anything else about it.
Ok, so we can't rely on humans. Let's consider the universe.
Theists like to assert that the universe itself is evidence that a god exists. But when we look at the universe, do we see a god? No. Do we see something resembling a god's signature? No. So what do we see when we look at the universe?
We see....a universe; a universe working all on its own, seemingly without any need for a "god" to explain its operation. Galaxies turn, stars are born and die, and energy is transformed all on its own. IOW, the universe looks completely natural.
Ah, but theists say, "What about how the universe came to be?" Well, the only honest answer right now is "we don't know how it came to be", but that by itself is no reason to posit a "god". So why exactly we should posit a god in the first place is unclear. Is there a means by which we can differentiate between a universe that was created by a god and one that "just is"? If there is, I haven't seen it.
So, using logic as S-U suggests does not lead us down the path of concluding that a god or gods exist(s). And of course, none of this takes into consideration the fact that "god" is--at best--a very poorly-defined term. What exactly is "god"? I suppose that's something the theists will have to answer (and not solely via bald assertion either, but with supporting evidence).
