Such a civilization would have already got had a rare period of time to develop. Such a civilization might theoretically have developed applied sciences far past something we presently possess.
It might probably have developed for instance: superior synthetic intelligence; autonomous machines; genetic engineering; nanotechnology; self-replicating programs; autonomous spacecraft; planetary engineering; Interstellar house journey: superior power programs; telepathy, time journey; applied sciences able to modifying its personal biology.
They could have began as organic organisms. However after hundreds of thousands of years, they may have turn into one thing else fully. A civilization that’s partly or nearly utterly post-biological.
Organic evolution and technological evolution might turn into intertwined. The civilization would possibly start altering itself intentionally. Its members might alter their biology. They may change organic organs. They may combine synthetic intelligence into themselves. Finally, the excellence between organism and machine might start to vanish.
We name them “aliens” and their craft “UFOs” just because we don’t know who they’re or what they signify. However what if that’s the flawed method to have a look at them? What if they don’t seem to be one thing mysterious in any respect, however the results of their very own evolutionary journey on one other planet?
Simply as humanity has advanced from primitive instruments to superior know-how, synthetic intelligence, genetic engineering, and house exploration, might these beings signify what humanity would possibly in the end turn into after hundreds of thousands of years alongside its personal evolutionary journey, formed by the applied sciences, developments, and methods rising right now?
Simply take into consideration this: If humanity had been to come across a civilization 100 million years extra superior than us tomorrow, would we even acknowledge it as a civilization, or would we merely name it one thing we can’t perceive?
