The purpose of life is whatever you want it to be
It is not worth discussing whether or not a certain life was purposeful unless there is a certain specific reason to while away time and in the process not be certain why one should consider the purpose of life of some other person when we are not certain of our own imagined purpose
If any life form is born, lives, copulates, has offspring, dies that life was purposeful for life itself to continue unhindered...
