What do you say to somebody like me who HAS shared in that experience and dismisses the believer's interpretation of it because of what he learned then? I once would have told you that I knew God (the Holy Spirit) directly and immediately. I became a Christian (formerly self-identifying as atheist) in the service. It was a feeling that was most intense during the church services in that, my first church. It was a feeling of warmth, connectedness, and belonging, and my charismatic pastor was able to whip his congregation into a euphoric state singing, standing, clapping, shouting out amens.
It was only after discharge and my return to my home state, when I tested about a half dozen other congregations, and found them all to be dead that I came to understand what I had actually been experiencing and misunderstanding was a product of my own mind and not what I had thought. If it had been the Holy Spirit before, and if the religion were true, it would have followed me. Today, I understand all claims of experiencing gods in that light - people misunderstanding spiritual experiences and an attributing a loving, conscious agency to them.
I still have that experience - fairly regularly - but I don't interpret it in terms of gods anymore.
Assuming that they aren't just saying what they think they are expected to say and actually sense something they are calling a god, my answer is the one I just gave. They are misinterpreting spiritual experiences. I proposed to my future wife early in my Christian walk while sitting on the barracks step when suddenly, crepuscular rays shone down through the clouds, and almost as suddenly, I understood this to be a message from God. I was predisposed to think that way.
The marriage was terrible and ended in divorce not long after our return home from the military after I had time to understand what had happened and realized that I was in a bad marriage with a frigid, eccentric woman incapable of love or affection. That's what faith also has people doing. Happy ending: I remarried, but this time based in evidence. This time, I knew her. I had lived with her and has sexual relations BEFORE marrying, and made a decision based in evidence that time. That was 33 years ago, and we are still happily married and love one another.
Do you mean the impact of such belief or impact due to gods themselves? Probably.
Yes, the belief has impact in many lives, sometimes for the better. We have at least three RF posters who owe their sobriety to AA and a god belief. It makes many trust in faith, read Bibles, pray, go to churches, and give them money. You can judge for yourself whether that is good for them or not. It also makes some homophobes, atheophobes, misogynists, and anti-intellectual. And you just read how such a belief impacted my life.
You've asked several times. You probably realize that if you don't get an answer after two tries, you won't. So what to do? Keep asking? Drop it? I've chosen to just answer for them. I tell them what I believe is the correct answer and offer them a chance to correct me if they want to, which would be the answer I was seeking. Either way, the matter has come to a resolution. It's hard to believe that if one's offered answer was way off, that it wouldn't be corrected, or that if it isn't corrected, it wasn't on target.
Let's try it. Instead of a fourth or sixth round of "where is your science for a god," change that to, "You have no science. If you did, I'd probably already know it and be a theist myself, and in case I didn't, you'd have posted it already." Now, you've come to a resolution.
Why call that god given the baggage that word carries? As you undoubtedly know, Einstein used the word poetically ("God does not play dice") and it's still causing confusion.
That's the god of Abraham, who has billions of adherents across a few religions including the world's two largest.
He didn't ask you that. He asked why those who say they know gods exist think they know that and why they should be believed.
Same answer. He asked you if you say that you know gods exist, why you think you do so that he can decide whether you have a good argument to justify your claim.
Same thing. He's not asking you what you think you know, but why you think it's knowledge rather than a comforting, unfalsifiable claim.
You didn't ask me, but that is my definition of an atheist - a person with no god belief.
I call such a person an atheist. That's because I don't care how many people reject god claims, but rather, because I care about what fraction of the total hold them, and more specifically, what fraction believe in the Christian god (and vote accordingly) as we watch these religious self-identification surveys evolve. That interest will disappear once these religions have shrunken sufficiently that they only affect their adherents and volunteers and are pockets of theism in a secular humanist landscape with no more cultural hegemony that the Muslims and Druids, who to my knowledge have never influenced a Supreme Court decision or the outcome of a presidential election in the States, enjoy in Western democracies.
Should a small child be called an atheist? I don't care either way. It doesn't matter if you call him an atheist or not. And of course, dogs and rocks also don't hold god beliefs, but nobody cares or wants to define them in terms of god beliefs. Nevertheless, if we want to limit atheism to mean only those who have heard and rejected god claims, we can define it as the set of people who answer "No" to the question, "Do you believe in a god or gods?"
