Our cellular structure is a life within life, and such lower forms of life came first before building us (so to speak). Once upon a time there probably was a mud hole somewhere upon a new Earth with chemistry ready to spark life like a match ready to fire. Then, in that very, very, vulnerable mud hole, life sparked. And it promptly looked to spread itself to every other mud hole it possibly could reach. Practically instant evolution in having survival instinct. Since life is here in billions to trillions, maybe more, of variations from one cell up, including life within life (maybe even within that single celled creature) that in no way believes itself to be lower forms of life -- or is even aware that there are any forms of life existing higher than its own, I think it managed to survive quite well to spread and to evolve variation and complexity to even better survive and prosper. Now it has reached the ready point -- it has reached beginning point -- all over again. Deja-vu. History repeating so to speak. Does it expand out from this very, very, vulnerable planetary size "mud hole"? Or does it just turn inwardly to itself to await certain, inevitable, extinction, proving to life's nature that it is no real survivalist, no real prosperous, life at all?
Likely, if and when we reach out in expansion of life in massive amounts of life and energetic space based and faring structure, we won't realize that, then, we have achieved yet another evolution of life. We will be the life within the structure and infrastructure of a life that has become a life of its own. We will believe we are in control, well some will believe they are in control, and [that] life the next level up that we have been long energizing and sparking to emergence (to animation), will believe it is the aware and in control, when in fact the case will be a symbiosis between two levels of complex life forms that neither is aware of the other being aware. A few, a very few, in the lower level within may realize what has happened and throw up their hands saying, "Dammit! Our creation has taken on a life of its own!" Frontier-wise, it may not be a bad thing. No bad thing at all. Somewhere, probably many somewheres and times over, it may probably have already happened. That is, excluding our own mud hole world (our very local universe) and beginning billions of years ago, and us now on Earth at yet another threshold edge of (nova) beginning, of (nova) expansion to survive and prosper, or implode and go extinct (from implosion, if not from some other cause).
