This is not a philosophical or religious question rather a reality. Do we actually owe our lives or does it all belong to infinite intelligent/God? Just pause for a moment and have a little thought regarding causes of death, which includes but not limited to Accident, fire, gun, illness etc.
It's erroneous to believe that your life belongs to you because you might just wake one morning and someone out of a blue, who haven't met you before decides to take your life by deliberate or happenstance. people even die of overeating, over-drinking and some even during sex.
No matter how rich and secure you are, that can not prevail over death. It comes when least expected.. And after-life.. A mystery best told by you. A journey of no return..
