What is the ultimate purpose of the humanity?

you hit the nail on the head. people seem to forget the rules of nature, humans purpose cannot be to reproduce and destroy the planet by doing so, i don't see the point in this pursuit of preserving life, people need to die its a fact of nature, because if they don't, we run into the problems we are facing now. but as far as your question, i have no answer, i think about it all the time, everything has a clearly defined purpose, plants animals, all interlocking, humans seem to be aliens, or a mistake. sorry there is no clear answer, but i agree so much, i had to reply
