Young, there is a lack of "Self" (Insert in your opinion/proper term here.) in which with age, one accumulates, or unfortunately simply fails to grasp. This sense of 'self' is what drives the individual to learn, process information, and create thoughts. Throughout the ages, this phrase has stayed constant in its meaning, and has always (exaggeration) been present. We all are taken upon a journey, into history, where the benevolence of fate, time and space await us. Where we confront our self, and begin to consider, what if?
Before Ancient civilizations came out, there spanned the globe a simpler, yet more complicated man, so to speak. "In considering the theory of human evolution it is interesting to note that some very well known scientists have actually suggested that the line of human evolution is far from clear. For example, in 1990, Richard Leakey himself said that, "If pressed about man's ancestry, I would have to unequivocally say that all we have is a huge question mark. To date, there has been nothing found to truthfully purport as a transitional specie to man, including Lucy, since 1470 was as old and probably older. If further pressed, I would have to state that there is more evidence to suggest an abrupt arrival of man rather than a gradual process of evolving." (http://www.detectingdesign.com/earlyman.html, Sean D. Pitman, M.D.)
None of us know what humans so far back could have been thinking about, technologies were nonexistent as we know so far, a large social structure had not existed, again, so far as we know. A sudden leap in evolution, a skip, a break, here we all are. "In a recent lecture in St. Louis, Mary Leakey pointed out one additional feature of her footprints that one does not often see mentioned in the literature; all of the larger footprints of the trail have a smaller footprint superimposed on them! Mary Leakey herself conceded that it appears that a child was intentionally lengthening its stride to step in an elder's footprints!" Pitman noted. What holds back 'Humans' at such a point before any type of organized society, from free thinking, solving problems, and sharing them with each other. The origins of Mankind are a blur, others protest at such, but there is simply the question that we all should ask.
Who am I? Avoid those clichés of Media that insist you are "one of the following" as if the whole spectrum of humanity can be rolled up into a list. And you choose what type you would like to be, by filing them in. (eharmony.com)
So please ask the question again to yourself, who am I?
And in the process consider what you actively do, to define your thoughts, as in learning, thinking, questioning.
