I might be the only person in this thread that finds this news as unfortunate. Even if you cannot find a proper religion to fall back on, I hope you're happy identifying yourself as an agnostic. I was agnostic until I found Earthseed, and now I'm its leading advocate for it on this forum. I know, it does seem that religion makes up a lot of things, but that does not mean you cannot find common ground with others or attend a congregation once in awhile.
If you are content with agnosticism, I think you'll keep that title and stop searching. If you seek any sort of spirituality though, you won't keep that identity. I was not content as an agnostic, but I hope you are. And I don't want to project my feelings on you, so if your pursuit is truly over and you're happy with the way things played out, all the more power to you.
