another group of scientists who negate the existance of soul did an experiment in which they kept a dying patient in a box of glass and sealed it air tight. and you know a few moments later the man inside the glass container died ...but the container blasted with havoc and soul was released.if you dare to do it at your home...go do it.we need not to find a reason wether a soul is there or not,infact we need to know why it is there.
if there is no soul,then we are not supposed to be responsible for our deeds.the believers will believe and the disbelievers cant be forced to believe.
