I am not sure whether we can answer the question using human logic and reasoning because UFOs or UAPs do not necessarily act in ways that seem rational.
An intelligence born out of another ocean is liable to emerge from brains bearing no great resemblance to our own.
It is also suggested that at least some of our inexplicable but undeniable visitors are not from another star system in our universe but possibly from a parallel dimension or other reality.
If so, their thinking is largely inscrutable and may be based on different laws of physics.
I take this from the published “Skinwalkers at the Pentagon,” a bombshell book by the directors of the US government program resulting from Senator Harry Reid’s $22 million allocation back around 2010.
The authors are former US government employees with high clearances who had to submit the manuscript to the Department of Defense for approval before publication.
I think the reason why Lue Elizondo, former UAP project director for the DoD, said that if people knew what he knows, they would feel “somber.”
These guys are, in short, not Vulcans, Klingons, or Cardassians – they do not appear to be native to our reality.
They will probably not laugh at our jokes, and if they have emotions, they may be incomprehensible to us.
How could we make heads or tails from their use of lights, the choice of when to display them, and the colors and brightness?
Having said all of that, I would guess that if there is a rational answer, it would be one of these suppositions:
Visible light may be a natural outcome of the exotic propulsion driving the movement of UAPs.
The best guess by physicists is that they use gravity field propulsion.
Using ‘negative energy that our theories say may be produced in metamaterials like those reported to have been found at crash sites.
In other words, if it shines at certain times, maybe it is because of the mode of their technology.
It also seems that at times, they want to be seen, and at other times they don’t.
This is either for reasons that are beyond our comprehension or because there is more than one kind of visitor, each with a somewhat different agenda in our biosphere.
Maybe the light broadcasters want to encourage something, like nudging our societies toward disclosure in advance of an approaching open contact.
If so, because our breakneck technological advances are bringing us to the point where this can not be avoided much longer.
Government and ex-government personnel are in a position to know who has received classified briefings on UAPs.
This broadly hints that the government has a staggering amount of excellent photos, film, and evidence from other sensors that suggest at least some UAP operators are, in fact, trying to force the government’s hand – ‘get your people ready to have their world views altered.’
Or one group of them is trying to nudge us away from nuclear weaponry by mocking the military folks of all the nuclear-armed nations with their evident invulnerability to our weaponry.
Theoretical physicists seem to think this is because their propulsion technology warps space-time, creating a kind of film or bubble around the UAP that bullets, etc., cannot cross.
And I would be unsurprised if some UAPs show perfect imitations of human navigation lights.
If they are from a million-year-old civilization, then why can’t they also display lights, including FAA-compliant lights? If they choose, it is better to hide in plain sight.
It is open information now that some UAPs have demonstrated the ability to jam or fool various sensor systems.
So when they appear plainly, it seems to be because it’s time for us to get past the stupid and childish stigma that the US government created during the Cold War era.
With apologies, when I read someone’s knee-jerk skepticism, particularly if they are sarcastic or dismissive, I have to shake my head that they fell for the intel agencies’ disinformation campaigns and refuse to wake up.
Case in point: some of the “professional debunkers” have built their lives around debunking UFOs.
Some point to the confirmed Pentagon videos and say we just see lens artifacts from the cameras, ignoring the fact that the fighter jets were vectored to the spot by radar contacts made by warships and the fact that we can HEAR the pilots exclaiming, “Look at that thing!”
Clearly, these things cannot be a camera glitch if nobody even looked at the camera recordings until after the radar, and the highly credible eyewitnesses had eyes on the UAP.
It’s a critically important topic, and I think it’s better to look at it honestly now and get used to it rather than wait until we are forced to.
