I'll finish with a few things about my beliefs:
1) Religion, in general terms, is very good for humanity. Whether that be a system of morals, a specific denomination, or just a community, it generally is good. It helps to teach the young about morals, and imo, is no different than different variations of different parables like Aesop's Fables, Hans Christian Andersen, Mother Goose, the Bible, or whatever else. More importantly it creates a community. Take a look at any small town in Iowa and the most attended events are that of religion, bringing the community often in support or celebration.
Certainly "religion", as in Christian vs. Muslim vs. Buddhist vs. etc. may not be required for any of this, but people define religion far too narrowly, and in doing so lose sight of what it actually means. In fact, most people that claim to not believe in religion simply don't believe in a supreme being, as discussed at length in this thread. They "believe" in many of the exact same things as the religious, but refuse to follow a god, they still form communities of like-mindedness and come together for support and celebration, it is just much easier and "built-in" when doing so with a specific religion.
One of the things I think people like about being a member of a church is that they know that wherever they travel, wherever they move they will have like-minded individuals to make community with. I think this is vital to our human existence.
2) Respect for differing religion is important and must be protected. Humans have very emotional and protective mindsets that often jump to "us vs. them" attitudes and is extremely easy to do when religions have specifically built and designated places of worship. If this respect isn't maintained it is one of the easiest things to attack, and is shown such throughout history. This includes understanding that people believe things that are different to you, things you might not be able to reconcile or explain, and most importantly that they don't have to reconcile nor explain them to you, or anyone else. When you demand that reconciliation/explanation you question its very existence.
3) I don't know and neither does anyone else, which is why people have "faith", whatever that may mean. As I've said above, the existence of a god or not does not rely on our beliefs, nor does it rely on our comments or prayers.
Most importantly of all, imo, anybody who believe they can disprove someone elses faith or god is an ignorant, self-righteous fool.
