Are we living in an age where religion is soon diminishing?

I think people just need something to do on Sunday, and church is a good excuse to get out of the house. What most people don't realize is that religion is just a tradition that people use to practice their spirituality with. If people find a better way to celebrate life, then past religions will become obsolete. The way I see it; a common church for a community to gather at, would be a good thing. But, religions that were conceived by people who hung each other on crosses, would be a bad thing. Religion needs to evolve to the modern world, just as the economy should.
