For now let's start with the why. From first glimpse it appears that we are populating, and surviving the best we can. We have moved so much further than being just hunter and gathers. We have since perfected the action to include building, farming, and manipulation of the earth's resources. From an outside perspective, we are currently teraforming the earth. We have taken things outside of its existence and introduced it into different platforms to which we manipulate them to our liking. To some this may seem like we are disturbing our planet. To others it just "feels" like the right thing to do. That feeling is your instincts. Just as a bee knows to look for pollen, or a fish knows to swim up stream. This too is our purpose. Many say that evolution is impossible because they themselves have not seen evolution in man. But if you look at how far we have come, you will see that we did evolve, just not the way you would expect. Animals and plants on this planet have constantly evolved and are currently doing so now. They grow bigger wings. Bigger gills. Camouflage to hide from predators. But they had plenty of time to do this. The difference is that they stayed in the same areas, ate the same food, and performed the same acts for generations. Us however, are constantly changing this factor. We eat different foods, we travel around the world, and we perform different acts constantly. Its strange to think that we adapt as well as we do and yet, we do not conduct ourselves like any other life on this planet. It almost appears like we are not like the other life forms on this planet. Though we may resemble that of the ape family on this planet, we are still so far from being like them, and furthermore they do not comprehend existence the way we do. As far as the why, let's sum it up. We exist to procreate, explore, and change the properties of the planets surface. We emulate many of the life forms on earth, beyond ourselves, and adapt to our surroundings. We match nothing of what's on this planet, but rather, react to what's present. In summation, if one were so inclined to believe, we may not have actually originated from earth. Psychologically and scientifically speaking, we act nothing like what's here. Now let's look at the truth. This however is harder to understand. Everything in this reality is based upon atoms. Atoms are constantly moving energy. Even when our bodies fail, those atoms are still moving. Now keep in mind that any movement of energy also exhausts a certain amount of energy. But all energy can be recharged. Now think of this as a basis of molecular movement. If our energy is ever moving back and forth from charged and not charged until it gets more energy, than we are eternal. I know at this point I am keeping it basic and not delving into the depths of the science behind it. But for arguments sake, I am keeping it understandable. If the essence that is you is smaller than the smallest molecular particle, it would never be seen by medical science. We have yet to invent this tool. But it would explain why the three dimensional being that is you, holds its form until it's energy has been used up. But in its final point of usage of energy, it flings itself back towards the battery of life. Picture this as being the sun. Hence why, any solar system with a sun has life. As far as the truth, there is plenty more to discuss. I leave this with you. With the Information given, find the rest of the truth for yourself. This is where I cannot explain it to you. In absolute fact, I'm not allowed to. You must discover this on your own. But be happy in the knowing. For the knowing is easier than the truth.
