heaven could simply just be a more "positive" outlook on annihilation, for all i care, codified in terms more appeasing to unsuspecting followers. we know nothing about heaven, forget hell. we know more about hell than heaven, that is the only appeal. there's a lot in this present life care about more than a heaven they know nothing about. they are in love with the fruits of this world, their lives, their families, their countries. they only know this life, not the afterlife.
