Amazing.
This is just so... amazing. It makes you think about how everything any of your history teachers ever taught, how every single one of our greatest accomplishments have happened right here on this insignificant rock we call Earth. That time you stubbed your toe, when he didn't call, when she made you feel like the most important man in existance, each and every precious childhood memory you have ever had has occured on Earth. As humans, we have a tendency to think of ourselves as so big, the dominant species, as important. If we just had a better concept of what "big" is. And I completely agree with CloverGreen. There is no way anyone could possibly argue that we are all the life there is, and if we are, what a waste! And what if the universe, the biggest thing we have ever known, is not where it ends? What if, by comparison to another body, the universe is not even able to be called sizable? What if it turns out to be just a speck in the eyes of something larger? And I believe that it is possible to be able to cross the universe in a matter of hours. Sure, it seems unlikely, but I would be willing to wager that in the 1700s people would laugh in your face if you mentioned planes, automobiles, or space shuttles. Our sciences have improved to unbelievable levels yet they still have so far to go. If we can get so much done the way things are, imagine what we could accomplish if the Earth, as a whole, would join together hand-in-hand to work towards a goal instead of just bombing and warring each other. Sure, we come from different places, like different things, speak different languages, believe different things, and think different things, what we have in common is so much more important. We are all human beings. On the outside we are different, on the inside we are all the same. If we could see this, the world would be a much better place.
