Denial is a psychological defence mechanism that psychoanalyst Sigmund Freud described as the refusal to accept an uncomfortable fact or reality.
On the other hand, Occam's razor is, to paraphrase, the simplest explanation for any phenomenon is usually the best explanation.
If you see a light in the sky that you can't immediately recognize, why would you assume it's a "drone" and not a normal aircraft?
If you cannot definitively identify the light, you cannot deny the possibility that it could be any or all of the following;
- a Martian spaceship,
- a star,
- a satellite,
- a normal aircraft,
- a "drone", or
- anything else.
If, as shown in most media reports, it has lights like a normal aircraft, moves and sounds like a normal aircraft, then it most likely is a normal aircraft.
Why are people seeing those lights as "drones" instead of normal aircraft?
If it's a solid light that appears to be not moving, it might be anything including;
- a hovering alien "orb",
- landing lights of an aircraft coming toward you,
- a "drone",
- a streetlight on a pole at the end of your driveway, or
- anything else.
Someone may yet someday produce incontestable convincing proof that all of those (as yet) unidentified lights in the sky are, in fact and reality, actual Martian spaceships.
If that ever happens, it certainly will be an "uncomfortable" awakening for the skeptics among us. But, until then I'm sticking with Occam's Razor and healthy denial.
