We love to tempt her, toeing the line of our possible demise. Inviting, daring her to pluck us from the narrow edge of this razor we tread and call Life. How silly this sounds upon reflection, knowing we can t take any baggage on that final journey. Science just as adamantly denies it. The universe wastes nothing, uses everything.
Every part has a purpose in relation to the whole.
What is useless is expended. What fills a need is kept. This is justice indeed. So it is plausible that if, in the life of a being, they become useful and really individually useful, not just as a part of some larger function they will continue at another plane of existence. Despite grandiose notions of our personal importance, from the cosmic perspective, single humans are only valued as part of the great mass of Humanity which fills a role in the cosmic scheme.
