This may sound rather shallow but I don't mean it to be.
Could it be that Christians take the whole thing of 'Life' more
seriously than atheists who, after all have no point in living
beyond the 'extended moment'? If Christians believe the
bible, it's very serious. Jesus said 'blessed are those who mourn'
and I'd say there's plenty to mourn. Yet we hear so many
just joking, finding life a big joke. Maybe that's because
for them there is no important reason for anything.
