I think it was on T/A that I read someone's response to a Christian who was rationalizing his religion. The dissenter pointed out that even among the other religions, Christianity is one of the least plausible, with "X" religion (I don't remember; something I had never heard of) being the most plausible.
I think that's an interesting thing to think about. Which religion do you think is the most plausible?
NOTE: Perhaps I should word it this way: which religion is the least preposterous? If I asked you to rank the religions (atheism is not a religion) by most plausible to least plausible, you would rank "1. X, 2. Y, 3. Z" and so on. You would not say "none of the above" because I'm not asking "which religion is plausible." I think we can all agree that none of the religions are plausible (at least not plausible enough to accept because, well, most of us here on Think Atheists are atheists :D)
I briefly looked through this thread, so forgive me if this has already been mentioned. Of any religion, I think Deism is the most plausible. A Deist believes that there is a "God", but it does doesn't involve itself in the universe (i.e. creating miracles, listening to prayers, speaking to people, etc). Many of the founding fathers of the USA were Deists.
I think it's understandable to take this position given our limited perspective in the universe - especially 200+ years ago. But as we learn more and more about where the universe came from and where it's going, I think it's increasingly difficult to say that there is a "God" behind it all.
