No, you know what? I'll give it a shot.
We all come from the same place, the same whatever-it-was before the explosion at the beginning of time that is commonly referred to as "The Big Bang". From the same singularity, the same infinitely compressed thing, we flew out into the universe at speeds beyond imagining. We are all part of the same stuff, made of the same materials that have simply changed how they seem over the course of countless billions of years. In that very real and meaningful way, we are all one, and connected. The air that touches my skin, the keyboard under my fingers, the wires that send this information are all from a single source, not truly separated. A star that burns billions of light years away from where I sit at the moment is connected with me, you, and all other beings and things in the most primal and fundamental way possible. Every atom in your body existed back then, and will exist until the end of time. This holds true of every atom in the universe.
The energy that was released in this explosion is the same energy that causes my heart to beat, my synapses to fire, the electricity that runs through the wires, the blood to course through your system, and the nuclear explosions in the sun that I mentioned in the preceding paragraph.
Therefore, we are all one, and there is nothing that we can do to escape that fact. Stemming from that, we have developed a fascinating ability to observe and investigate all of these things. We are endowed with the ability to reason, to strive, to push further into the unknown.
And as we are all parts of the same origin, we are that part of the universe which is capable of observing itself.
We must get along to the best of our ability, because to harm another is to harm a part of one's self.
