I think it is safe to say that any and all of the "revealed" religions on earth today are about as reliable intellectually as a watch thats been trampled on by an elephant. I also am amazed that some could actually still be Christian after the WT. I mean, your average born-again is just kissing cousins to the JWs in terms of theology and outlook. When I left the organization I left the Bible as well. It was like a double-helix of doubt that drove me away. So, I'm with you there.
On the other hand, I do feel a certain "religiosity" about some things in life. I find Buddhism and Taoism interesting, although I cannot bring myself to believing in them either (Taoism is more a philosophy than a religion, though. Buddhism has many sects, some of which are totally ludicrous to me). The "new age" movement is nothing but a hodge-podge of looney ideas complete with silly elevator music. All rubbish.
But, I cannot proclaim myself an atheist. Agnosticism seems to me the most intellectually honest position to take. Sure, I would be thrilled if there were a God(s) and an afterlife. I see no evidence supporting these notions, though. The only bit of evidence for "God" I see comes from the world of quantum physics which states that certain natural phenomenon need a conscious mind to observe them to take place. Don't ask me for details, but I've read this. Amazing and "mystical" as this sounds, some tests tend to confirm this notion (for instance, depending on the conditions an observer will establish, light can be either a wave or a particle. Weird,huh?). Of course, this is also debated by many physicists. There is just so much we don't know.
Personally, I would like to cultivate some type of "spirituality" in my life. Perhaps a blending of Taoism, Zen, science, philosophy and Deism? Whatever it is, it will not be a "certainty" which might be a good thing since having "certainty" sets one up for massive dissappointment. Been there, done that.
