I remember watching a TV show called Sightings once upon a time, which was about sightings of ghosts and/or aliens. The particular episode I remember watching had various witnesses of a UFO sighting saying they saw a craft in the sky that was big, black, boomerang-shaped, and made no noise whatsoever as it slowly flew overhead.
I remember this episode because of the day I took my ASVAB test (basically an SAT test for the military). When we got to the base, I saw a military aircraft in the sky that was big, black, boomerang-shaped, and made no noise at all despite how close it was unless it was landing or taking off.
It was a B-2 Stealth Bomber. The people on the show saw a Stealth Bomber and immediately thought it was an alien spacecraft. It was in that moment when I saw that B-2 that my skepticism, of any and all alien visitation testimony as ludicrous, was cemented as justified.
JEDIT: Also, I remember my high school physics teacher discussing the topic of aliens, where he said given the billions of stars in just our galaxy, and the millions of galaxies in just our local supercluster, and the enormous number of galactic superclusters there are just within our viewable range of the known universe, and how unknowably large the actual universe itself is, that the probability of life on other planets is extremely high.
And, given that, if you take into account the number of planets we can observe that can support life (including our own) and run the math to calculate: 1) the number of life-supporting planets that do actually have life; 2) of those, the number that has intelligent life; 3) of those the number that has life approaching the capabilities of our own; 4) of those the number that has surpassed it; 5) of those the number that has the capability of manned interstellar/intergalactic space-flight; 5) of those the number that could come here; 6) and of those the number that would want to…
And so, while the probability of life on other planets is incredibly high, the probability of them visiting us is infinitesimally tiny. Never mind that Trump couldn’t keep it to himself if someone told him about it.
