@littlek,
Perhaps greater forms of life are the evidence that bacteria/microbes may have initiated, shaped and facilitated the evolutionary process. The human body could be a masterpiece of this tiny at times imperceptible layer of life. I personally believe that atoms electrons, protons, neutrons etc are life forms also and not just static elemental particles.
Atoms breath and are arrayed into their own chart that mimics a tree of life much like the animal kingdom. I have entertained the ideal that rocks are alive. Perhaps they communicate through gravity. They did not evolve a mouth or physical vocal apparatus because they did not need one to communicate on that level.
Perhaps the "?aliens"? are living around us and we have not learned to interpret their cryptic infinitesimal way of communicating. Perhaps they are closer than we think and the use gravity to talk to the mother ship.
These aliens/microbes are in us they are all over our bodies. They penetrate the deepest forests and oceans of the earth and beyond. They live perhaps even in the center of the earth and sun. They may even peacefully exist in the center of a black hole. Perhaps microbes trigger earthquakes and tornadoes they are at the center of hurricanes and live deep within the core of volcanoes. These microbes are in the chemicals and the synapse of our own thoughts and energy life force. Our survival instinct comes from this tiny seed and connects us to the consciousness of the overlord.
These microbes/elements are orchestrated maybe through gravity and neutrinos and quarks by perhaps a brain element or monolith that controls the entire earth and/or universe like Gaia.
