A viewer asks: “The hybrids and clones were said to be able to live into the hundreds of years. How can they avoid not being discovered as staying youthful for that much longer and spanning many lifetimes?”

The robotic Greys function for hundreds of years, but this is not truly a lifespan as they are not living soul-based biological creatures but artificial intelligence with a biological covering. The hybrids are a recent development and because humanity has a short timeline now, people will not be around to see what those hybrids might be doing if still in existence somewhere. Their makeup is such that they do not enjoy the full longevity of the Arcturians of which they are a part, and nothing has been done to correct the human component that is reducing the inherent longevity on the human side, so they are not blessed with great longevity themselves.
