So Ill guess Human's purpose is to set the fastest record for a worldwide species extinction?
Nope, I'm afraid countless obscure species already beat us to it. (Or we beat them into it, or ate them, or poisoned them, or gave them diseases...)
In my opinion, humanity's purpose wouldn't be any different from life's purpose, which i'm not going to hazard a guess at. Anything that makes us different from other beings is simply our different way of trying what works best in the process of living. we might yet find out that it doesn't work and indeed bring ourselves to extinction.
