Couldn't you say it about any claim then, like the ever-evasive Bigfoot, for example? Do you bother with details about Bigfoot?
Yes, and people do bother with details about Bigfoot. There are also people who've claimed to see Big Foot.
Have you seen God? If not, then what exactly are we talking about?
I know of people who have. From their testimony, I can say that people have seen God, and I find their testimony trustworthy. That testimony is in the Bible.
Sure. Provisional knowledge is pragmatic, and that's my point. If God can demonstrate, or if someone can... that's great! I'm all for it! I'd love that, actually. The same is the case for Bigfoot or Nessy.
The problem is that it didn't happen yet, and including Bigfoot as an exhibit of the museum as some possible reality doesn't make much sense, does it. Why would it make sense in case of religious claims?
Religious claims don't have to be accepted by everyone. If someone is convinced by the arguments for Christian theism, and it's more probable than not that Jesus is the Risen Lord, that's good enough for them. As for God having not been demonstrated to be real; I'm convinced that he has been demonstrated to be real through Jesus.
Again, Bigfoot and chupacabra are both believable. Is it relevant in respect to our experience of reality? Not really.
The same with God and religious claims. Whether these claims overlap with reality... then religion becomes viable and useful. And in many cases it is. Religion can provide grounds for community, art, philosophy, health. But when it doesn't (think YEC, and homophobia, and etc), then why should anyone care based on inconclusive belief claims?
I think that the common denominator in all religious experiences isn't God, but rather people. Hence, it seems like a way for people to find meaning and act in accordance with that meaning.
People have claimed to have found evidence for Bigfoot, chupacabra, and God. It's just the case that not everyone finds the sources to be trustworthy for a number of reasons including bias against belief.
You yourself just said "Religion can provide grounds for community, art, philosophy, health", so it is viable and useful.
And if Christianity is true, is very useful when applying practices to avoid hell, and enter heaven. Quite useful.
As for homophobia, and YEC, those don't really have much to do with the claim that God exists, or the claim Jesus rose from the dead.
