A year ago my son's brother-in-law was killed whilst crossing the road on green at a pedestrian crossing in Australia. The car driver was on her phone and ploughed into him. He was only young. Tragic.
When we die (some of us) hope for some kind of life after death. No-one is really sure, but probably we just cease to exist as we did in the billions of years before we came into existence. What chance we were born at this time on this planet? One thing is certain: we know very little.
Are all religions our attempt to come to terms with our mortality? I do not know. No-one is really sure.
