I can't see it either, and I'm not a total pessimist. I listen to all the philosophical debates etc on the radio and the general conclusion really is to prevent things happen as much as possible, as there will always be someone about to start a war (by war I mean that from something massive right down to a local spat with a neighbour) , the trick is to moderate the situation as much as possible.
A never ending job, but that's the way mankind is.
As for praying, I've said I would to people, it makes them feel better, even though as a non-believer it's all illogical to me.
Years ago I was contacted by a relative of an online friend who'd disappeared. We'd chatted most nights and suddenly he wasn't there anymore. He was somewhat older than me but was a great guy. He'd died
She wanted to send me a prayer card and it would have been cruel to have said no, so I was happy to make her feel happy.
