Okay, here goes.
1. "Real" UFOs represent an extremely advanced non-human technology utilising programmable matter in the form of living machines; devices that can repair themselves, change shape and replicate. These devices are under the control of an extremely advanced intelligence that is similar to sentient godlike AI. They exist in a world of information beyond our time and place (even from the future) as a natural part of developing propulsion and associated technologies. UFOs can be associated with synchronicities or other bizarre occurrences where individuals are approached in isolation or at specific moments; for such an intelligence dealing with arrogant primitive, narcissistic simians, it's no problem, it's like a game.
2. This is the level of contact WE are capable of. Take a look at the map of UFO sightings. That's a lotof experiences.. We can barely accept other humans with different skin colors; few people can tolerate up-close interaction with alien devices on a regular basis. UFOs have maintained a level of contact over a very long time, without causing a "tipping point". Mission accomplished! The governments and militaries of the world know they are real, and growing numbers of the population. It's a game that maintains a certain level of acclimation. I believe these devices have been here for a very long time. Periodically they pass through our area, and it is easy for them to get here. We are an oasis of life that they have discovered or watched evolve.
3. If one supposes the intelligence has a deep understanding of reality, and one accepts the reality of the panop!y of "paranormal" phenomena, there is no reason to suppose it wouldn't have an understanding of that, too.
