Why is religious attendance declining

because people are realizing that religion is nothing but a scapegoat for what ever someone doesn't like something or cant explain something.

Religious Attendance is declining in some specific religions(You know which I am referring to, don't you?),these religions are declining because a lot of their people are followers just in name, most of them live in the developed world(the western world) and thus they recieve good education and they are raised in such an Environment where they learn to treat religion as rubbish for fanatics. But at the same time, One religion is thriving and expanding at a great rate, while as we know, the others are just dying.

I agree with all that ford_guy has said its true. A lot of people are beginning to believe in the idea of evolution and the big bang now. Some people are also just tired of the hypocratic behavior of some religions. Some people are tired of people saying they believe and follow one thing but they really dont.
