Just wondering - hoping you can shed some light on this for me - if Evolution IS in fact true - uhh.. what's next? e.g. what makes us think that we - in our human form - are "it"?

What will the next version of us be? Will there be one? If not, why? What makes us think we won't eventually evolve into an alien of sorts? etc..etc...


If we are at the end of the cycle, why?
