Humans main reason for existence is to be a tool to aid the survival of humanity.

What are we, mere mortals on a heavenly earth capable of producing and destroying life? What does this earth, our existence and humanity ask of us? What are we doing here? What is our purpose? The answer is that we are a tool, a part of the human race, merely one of the species trying to keep us going. No race has or ever will be created that has not got the will to survive, although within a race there may be beings willing to die. However when it come down to survival the real decision is inevitable. If one species has to be destroyed, we will make sure that we are the ones still alive at the end. Our genes won't let us decide an other way. So if we don't kill every last opposing species and if they can, they will kill every last one of us. Therefore all humanity asks of you, me and the rest of mankind is one simple request. Humanity does not ask anyone to be happy or content, but merely asks you to be brilliant on its behalf. This is to keep all humanity alive Survival first, then happiness as you can manage it. To survive we depend on humanity as a whole, like a body, the ultimate tool. Every now and then, the body is groomed; week ones are removed and otherwise execs individuals are trimmed, and removed from existence For example, in the world wars, famines and other natural disasters. The tool keeps itself neat and useful at all times. And as a result we wait constantly for humanity to produce a creature capable of saving the humans from our own mistakes and self destruction. What we need is a Perils or a Demosthenes. Someone who sees that there are times when the world is rearranging itself and at times like these, the right words can change the world. The only problem with Perils and Demosthenes is that they ruined Athens twice. We need a Lenin, Bismarck, a Tomas Paine or a Ben Franklin. Someone who spots when the world is in a flux, and at that moment what matters is the right voice, in the right place, at the right time and you can move the world. Humanities job is to produce a Napoleon, an Alexander, except that Napoleon lost in the end and Alexander flamed out. WE need a Julius Cease, except that he made himself dictator and died for it. Humanities job is to produce such a creature and all the men and women this creature needs to help them. For if there is no one and a situation does come up, humanity will be woefully unprepared. It wouldn't't necessarily be the world at stake but humanity and then as far as the rest of the biosphere is concerned we could be wiped from the planet and everything would adjust and would get on with the next step in evolution. We are now straining and straining to give birth to geniuses and we have done so before. The person who made the wheel, who discovered the light bulb, the one who made a town, a city! To put it bluntly, human beings are free, except when humanity needs them. We may all do despicable things, but if humans survive we have been a good tool, because we are all tools which the others use for, the greater good, to help us all survive. Take what pleasure you can from living, but survival always will and does come first. Winning, survival, is everything, because without it, there is nothing.
