I admit I'm uncertain about my pick, but I think it could be possible (if highly unlikely) that we could someday find proof of whether or not God exists. We may not have anything to prove one way or the other the way things are now, but that's not to say we definitely never can. I'm not necessarily saying this will ever happen, but I think there might be a slight possibility.

I have over-analyzed the whole concept of the God of Christianity and have finally just decided/chose to believe it can never be proven whether or not he/she/it exists or not.

It can never be proven one way or another whether any sort of higher power or deity does or does not exist. If people choose to believe that they/he/she/it does exist, that's fine, and if not, that's fine too. That's why it's called "belief."

Maybe we can't know but there are people who can and do know.

We can never find out for sure while we are still alive. The only way to find out is to die. But you can't ask a dead person what they see.

I really don’t think people will have the answers of whether a god exists or not,religion cannot give concrete proof of the existence of a god while atheists also cannot disprove his existence altogether.
