Considering that reproduction is a core, though not an absolutely vital, part of the human experience that runs very deep into our mammalian evolution, it's not a false sense of purpose.
Reproduction is the purpose. That's it. Congratulations, you're now in possession of the somewhat white elephant gift of consciousness.
What you do with it is up to you. You only get one seat at the table, a starting hand, and some dice to roll each time you make a decision.
Why not play for a while and see how your game unfolds? No there's no official instructions but many people who've played before have written various guides, perhaps some of them will be useful to you. Maybe help others with their game, they're likely to return the favour.
You've got eternity to do nothing when you leave your seat. Might as well do something while you're sat here.
