Regarding the fallibility of witness testimony without getting into how it is indeed used with circumstantial evidence to prove cases in court, I think it depends on the specific circumstances.
Circumstantial evidence is still evidence, e.g. a footprint or a plausible motive, which must then be linked by a logical step (rather than other evidence) to the case being presented. The balance of probabilities is what carries the weight.
Circumstantial witness statements can be useful, e.g. "the defendant who was always complaining about the cost of living suddenly started to splash the cash". It will carry weight if the defendant cannot show where this cash came from.
Imagine if a hard-boiled detective gave testimony like "in my gut I know this person is guilty" without being able to present compelling evidence to support this position. No self-respecting prosecutor would even dare to present it to a jury.
If three other detectives testified the same way, would it add any weight before a jury? They have no choice but to focus on gathering and following the evidence. The burden of proof doesn't change based on personal feelings and instincts.
I guess I should say that I am pretty sure it can't be debunked; but I am open to the possibility. I just don't know what mundane objects they could all possibly be. Many of you are certain everything can be debunked
Considering the balance of probabilities is what skeptics do. Is it unreasonable to begin a "lights in the sky" investigation of a report, photo, or video against known phenomenon before leaping into the unknown? Can we proceed further if the information is scant?
I can't think of any regular contributor to this forum that believes every sighting "must" have a prosaic explanation. That goes against the principle of following the evidence.
I've proffered my experiences to skeptics for years and not been successfully debunked. The experiences were so amazing and unlike anything I have ever seen or know of. Why do I think they were interested in me? They isolated me on I-5.
I've read the two sightings in your About page. The first in 2010 is reminiscent of a tight formation of military aircraft. You were driving south. If they were flying SSE, they would appear almost stationary, and gradually cut across your path from the right (where you first spotted them) to your left (when you saw them again).
In that direction is the Kingsley Field Air National Guard Base where the
173rd Fighter Wing has been flying the F-15 since 1998. Camouflage is supposed to make them hard to identify from a distance. Being non-stealth, the jet engines would remain prominent from the rear, especially when the afterburners are ignited.
Military aircraft in decades past used to have bare metal finishes making them highly reflective, which could also obscure the detail. Could it be a heritage flight of aircraft?American Airlines also retained a legacy polished metal livery until 2013.
Your second sighting has little to go on. It is reminiscent of either a satellite or meteor.
Since I wasn't there, I can only work off the details you've provided. To argue "it could only be otherworldly" in court would require the jury to accept a logical leap over the equivalent of the Grand Canyon, and an exceptionally talented prosecutor
Nobody here wants to detract from your own experience, that will always be your own.
