I'm not sure I understand the question, but I think I would agree with both of the earlier answers. It seems unlikely that death will be abolished anytime soon (if ever); assuming that death is inevitable, then a return to nothingness seems likely, at least for the physical body. Or perhaps I should say a "reabsorption into the physical universe." Whether there is a non-physical spirit that survives death is, of course, a very open question until absolute proof of its existence is provided.
Someday science might be able to allow humans to live forever, but I don't think that's really likely to happen. Science has certainly extended the life span for most humans, but this has come with its own consequences. Have you ever seen the movie Aeon Flux? It deals with the idea that we were made to die. Our brains and our bodies cannot handle living forever. There are several books, movies, and philosophies about this. We also have to consider the question that even if science can move our though patterns to a computer or clone us into another body, would you still be you? What is it that makes us "us"? I would have to say that no matter what religion or scientific perspective you choose, there are no easy answers. Right now, the human direction is from birth to death. Depending on your religious beliefs, the human direction might be from Earth to Heaven or other afterlife. Eventually, science will have to answer the question of immortality, but we as species just aren't ready for that yet.
From the minute one is born, they are moving toward their death. While, for some, this may be a very long time, for others it may not.
Outside of that, I think that, more and more today, the direction of the human being is that of what they make it to be. Humans are becoming more aware of health issues, impact on the environment, and the importance of the struggle. Given that, I think that the world is far to full of "individuals" to make a globalized statement. In reality, the only one I can really think of is death.
You came from nothing and you are going back to nothing. So what will you lose?
It is very likely that there isn't a big 'answer' to why you exist. You are an evolved collections of molecules and cells. You must find your own direction and accept that the universe is extremely big and you are extremely small.
