A blink of an eye

I don't know if you can understand me when I say that there are moments in your life which may change you forever. As far as I'm concerned, this happened to me when I was fifteen or sixteen years old. In particular, studying my textbook of Natural Science, I read that the length of the human history could be compared to a blink of eye in the history of the planet. In other words, the past four millenniums are just a tiny part of the history of the planet. Although we are used to considering the human history as the most important, if not the only, part of the world history, actually, our presence on the Earth is a recent phenomenon.
As the first immediate consequence, it becomes clear that the mankind is not so necessary as we generally tend to believe. Since the world has been survived well survived without human beings for a such long period, evidently our existence doesn't make any difference. Contrarily, we could learn a lot about this evidence, modifying some of our behaviours which often are totally disrespectful of the natural environment. To sum up, I strongly believe we could consider all we have as a valuable gift and never forget that.

[Very good piece.  Minor corrections only.]
