I am chuckling a little, as over last night's dinner table we chatted about "scary stories." My BIL recalled -- with fondness -- the scary stories he was told over the campfire "way back when." And then another guest recalled her grandparents and their "fire and brimstone" stories of that era. Someone else brought up movies like "Halloween" and "Fright Night." And so on. We were, conversationally, off to the races.
About scary stuff.
As to space aliens and UFO sightings and wreckage, here is one salient point, divided into parts. If there are ACTUAL intelligent alien life forms visiting this planet, in truth, then even our nature of truth itself is suspect.
How about religious truth? Does Christianity apply to space aliens? How about Islam, so rooted in the sands of 7th century deserts.
How about science, so recently held up as truth, yet with competing opinions and theories. Space alien technology would far exceed our science.
How about political truth? Is something like "this" so shattering that we plebes must be kept from it?
How about all those branches of philosophy, winding their ways around understanding truth? Ontology? Epistemology?
Personally, at this time, I suspect we are either alone in the universe, or very close to being alone. Why? Adapting the curves of frequencies across the entire bandwidth of energy -- light, radio, x-rays, and all -- and bending these into an account of the red shift as Doppler affects how we perceive, there is a bandwidth of which our "betters" as aliens must be aware where there is little to no noise, and as such a very fine bandwidth on which to broadcast even a simple non-repeating signal. In that little trough, one hears nothing to date.
I am most willing to have my opinion changed, but not by speculation, opinion, and certainly not by "scary stuff" of Predator and Aliens and The Martians Are Coming.
Ray Bradbury said, more or less, all our stories about aliens are actually stories about ourselves. Sometimes the aliens come in peace, and sometimes they come to destroy. Depends on which story you tell, after all.
Being time-limited as an old codger and definitely biodegradable, the amount of CPU I spend on UFOs is little, and our courteous wee interchange of words and ideas has taken up much comparatively. Now I will go plant some more gladiola bulbs. Best wishes.
It is this very uncertainty that caused UFO information to be hidden from the public in the first place. They learned early on that most people wouldn’t be able cope.
