To shred the drape of these mortal coils that bind me thus turning me loose upon time

Death?

Procreation, the same as any other organism I’m aware of.. Interesting, though, we appear to be culturally evolving … whereas those of ‘childbearing age’ are choosing not to procreate (if not the act). Problem is, their cultural/ social ability for restraint will ‘die out,’ while cultures of ..rabbit breeding humans will replace them...

As for a collective goal, galactic domination

Beneath it all, the end goal is the perpetuation of one of the species, planets, solar system and eventually the one or more universes. Evolution is a complex system of which humans are only an very small part.

Closer to home I agree with twshield. I would add to that, concern for our planet, air, water, land and all living, (sentinent? Or is that too "Star Wars?" ); creatures

To be happy

Survival

Do the best I can. Harm as few people as possible. Bring joy to myself and others.
