Well, the strong atheist position is that there is no evidence that shows a God exists and if God did exist there should be evidence showing that existence.
Y'know, that's a rather arrogant statement to make. After all, to state that there should be evidence showing that existence, implying (or rather, outright stating) that such evidence would, of course, be accessible to humans right here and right now, and that this evidence would of course be utterly convincing to everybody, is problematic.
After all, as I wrote in a post just a few moments ago, black holes were imagined by someone in 178..6, was it? But it wasn't until Einstein showed up that there was any evidence at all for them (and then this evidence was highly controversial) and we didn't have actual objective evidence of their existence until 1964. ...and THAT was a fluke. I wonder what else is out there that is only predicted, without evidence, but actually exists?
God is certainly a more complicated concept/idea than black holes, the existence of which answers a lot of questions about the formation, life and death of stars. That there would be such things seems pretty obvious now. God, however? A very big subject, involving the creation of the universe and all....
and since the strong atheists I have come across wouldn't accept any evidence at all that would support the idea of God's existence, not even the direct appearance to them of God Himself to introduce Himself, I find it ironic that any of 'em claim that there is no evidence for one.
Well, there really isn't any, but these people wouldn't accept any if it did show up, any more than literal Biblical creationists accept any evidence for the age of the earth, the length of time it took to carve the Grand Canyon, or evolution. Just as illogical on both sides.
It is certainly true that a lack of evidence is not always evidence of the non-existence of something. But it *can* be the case that the lack of evidence *is* enough to justify a belief in the non-existence.
Of course; just like the lack of evidence for black holes for nearly 130 years justified the belief that they didn't exist.
The problem here is that strong atheists don't simply justify their lack of belief. They insist that there are no gods. Of any sort. That there not only isn't any evidence, there never will be any evidence, because there is no deity.
That is a positive claim, and the burden of proof is theirs.
.....and it is just as illogical for them to make that claim as it is for a theist to say 'there is a god and I can prove it."
For example, I do not see an elephant in my room. I do not hear, smell, or otherwise detect and elephant in my room. I can conclude there is not an elephant in my room because if there were an elephant in my room, I would *definitely* be able to see, hear, or smell it. The absence of a detection is then evidence of non-existence.
Oh, come on. deity is not an elephant.
Try this: I do not see any dark matter in my room. I do not hear, smell or other wise detect dark matter in my room. If there were any dark matter in my room, I would *definitely* be able to see, hear, or smell it. The absence of a detection is then evidence of non-existence.
The problem is, pretty much all scientists who deal with this issue figure that dark matter is all over the place, including your room; they don't think so because they have detected it (they haven't) but because, well, it 'must be' there in order for their equations to work.
But that might be something else entirely. Dark matter has been around as long as the universe, and we still have no objective proof that it exists, do we?
yet pretty much everybody figures it is, and they 'plug in' the idea every time they calculate something that would be incorrect without it.
So the question is whether a deity could be expected to have evidence of its existence. A strong atheist would likely say yes, it should. And then, the lack of detection does, in fact, give reason to a disbelief in existence.
Which is actually fine...just as it is fine to be a theist who says that there IS proof of His existence. Same/same, it seems to me. The problems only show up when either one of them makes that claim 'publicly' and expects others to take his/her word for it.
Now, of course, an argument needs to be given to show that a deity would be expected to produce evidence of its existence. It is possible to make an argument from omnibenevolence, for example, that a *good* deity would make its existence clear if belief had significant bearing on how someone spends eternity. That, of course, uses the assumption that a God is all-good.
I don't see how an omnibenevolent Being would HAVE to withold evidence for His existence, though I do see the evidence.
I also have to wonder about the definition of 'omnibenevolence' in the first place...most critics who go after that seem to think that being 'all good' means that God should make THEIR lives all gorgeous, RIGHT NOW.
I don't think that's what it means, any more than being good parents mean that children should have everything they want, as soon as they want it, to keep them from crying or throwing tantrums. Children raised that way tend to grow up with a very...slanted...view of the way the world works, and they end up very unhappy. If they don't end up in jail, that is. So how are parents who do that being 'good parents?"
