Whenever I find myself pondering about the core of the meaning of our universe (with a focus on our own existence), I come back to one generalization that frankly can't be reasonably disproven: if our world were to be destroyed today by war, unforeseen natural occurrings, or what-have-you, then the lives and existence of our entire species would not have mattered. At that point who lived, what they did and didn't do, and how far we've come as a species would have a relative amount of zero significance in the universe. Thus, what is the essence of living on this Earth? More so than even Freud had hypothesized, survival of the fittest is perhaps one of the greatest driving forces of life itself. The force that created the human condition made it inherently fragile: it's far too easy for a life to end. Another matter of concern is that there are naturally-occurring diseases as well as man-made diseases which leads one to realize that nature and the force that created the world doesn't work with us... or against us. Our civilization is fending for itself in every regard. With this in mind, I can only postulate that from a purely biological perspective the essence of our existence relies on survival of the fitest. This is why humans are the dominant species on Earth, why we have the genetics we do populating the gene pool, and why we have natural diseases. Survival in itself is perhaps the most important aspect of life from a biological standpoint. When we combine survival with the ability to freely think and create, what should we be doing? It can be easily argued that the essence of life is to push the human race forward. Yet, our ability to move us forward also has developed a tendency to move us backwards (i.e. nuclear weapons, man-made diseases). Our society is too concerned with where we could possibly end up when we pass and what created us that it neglects to reflect on what life truly is. What society created and has developed into is absolutely fine, but once we get to the core of life that doesn't matter. For the essence of life is perhaps one of the most bewildering topics... and also the single most important one. When we dilute life to its simplest form without all the additions that we as a species and a society have made to what should define it, what are we left with?
