I'm sorry to see the downvotes since this as an intelligent point. I'm not religious but one thing I do envy in my church-going friends is fellowship.
I'm a man in my 60's, and maybe all this is not applicable for the majority of folks here. But people don't have groups like clubs or bowling leagues very much anymore. Watching TV at home is fine, but not enough. (I'm in a club that is now breaking up, as these things do, and I think there is a very good chance I will not see these friends regularly again, which is too bad.) Of course, I could volunteer at a food bank, etc., but people I know that are in a church seem to find it more natural.
