I believe in what I want to
I believe in what I can see, feel, smell, taste
I believe in what I've experienced and what I've done and can do
But I simply can't believe that there exists a fictional savior of the world with great powers.
Even though. I don't see the big deal behind it. The usual believers are into it because they feel much more prepared for death then, when they can believe that there's afterlife. Even though that "god" doesn't have much to do with this.
