The constituent elements of our physical beings have been in existence ever since existence (granting symmetry) and all indications are that those same elements will continue on until there is no more existence, if that ever happens. It is just for this short little time in this tiny little place that said elements are imbued with what we call consciousness or self awareness but what a miraculous thing that awareness is. Where did it come from? With out it would there be no witness that any of this existed at all ( even if it is a debatable subject)? That is one point of view. Behold the soul of Man.
