So, are you saying that since, on the whole - people are not reliable witnesses that witness testimony should never be considered?
No, not at all. Witness testimony can be reliable, but should only be taken as such when it is backed up by hard physical evidence.

Are you saying that because there are a large percentage of people who can't judge things accurately - that means nobody can?
Again, no.
It will depend on the situation/circumstances, what is being observed, and how familiar/experienced an observer is with what he.she is observing.
For example, we are all (I assume) familiar with cars as they are part of most peoples every day lives. If an observer that falls into the
aforementioned category observes a car driving down a street in broad daylight, it would be reasonable to assume that he/she could reliably
judge/approximate size, distance, speed, etc.
This is partly because the observer has experience, but also because it is in a familiar situation where there are multiple visual cues, which help us
(or our brains - it's all done subconsciously without us having to think about it) to judge size, distance, speed, etc. Visual cues are things like,
parallax (which is useless beyond a few tens of meters), lighting/shadows and objects passing
behind/in front of other familiar objects.
Now, if you take away those visual clues (as is common with objects seen in the sky/at night), and the object is basically "a light source" (as many
UFOs are) of unknown
intrinsic brightness, size, and distance, the situation becomes much more complicated.
Lets say you see a dim (the brightness of a brighter star for sake of argument) light source in the sky. That light source could be light years away,
and extraordinarily bright if you were close to it, but since it is many light years away, and light falls off according to the inverse square law, it
looks dim. Now if you take a light source that is intrinsically not very bright, like a torch for example, and view it from a few hundred yards away,
it might very very well not look any different to the intrinsically bright light source that is light years away - there is effectively no way for an
observer to tell the difference between the two since there are no other visual cues, apart from brightness - but brightness can be misleading. Is the
object very bright and far away, or relatively dim and close by? Remember, we are taking about an unidentified object here - it could be any size,
brightness, or distance!
There is a problem with using brightness as a visual cue - since our brains interpret something as being bright as being close, and something dim as
being far away, which is fine on the ground and in familiar situations, but does not work so well with unfamiliar objects/light sources in the sky. A
meteor for example can be surprisingly bright (most people are not aware of just how much so), so when an inexperienced observer sees one, it's not
uncommon to report it as being very close, when in fact it is many hundreds of km away.
A similar effect can occur with satellites, which when they catch the sun and glint, can increase their brightness by a few hundred times, before
fading and seemingly disappearing. Of course we know that bright things appear to be close, and dim things appear to be far (this is hard-wired in
all our brains), so when an inexperienced observer sees a bright "satellite flare" (as they are known) it could easily be perceived as the
object "powering up" and then shooting off into the distance (sound familiar?).
For yet another example, try a search for how many reports are made on ATS of
"
scintillatilating stars". These are objects that are light years away, yet
people often describe them as if they were in our atmosphere or just outside it (a few hundred km away tops).
These are all examples of common optical illusions, caused by the way our brains work, and
no one is immune to them since all our brains are
wired in the same way, although more experienced observers may sometimes be able to see past the "red herrings" and identify the object correctly.
And this is also the reason why in certain situations, witness testimony is
very likely to be completely unreliable, and I haven't even
mentioned other failings in humans like
false memories, and
reification.

As long as you want to accept nothing that isn't accurate and provable - you must be saying that even if people all over the world are seeing
something - we must assume that all of them are in fact seeing nothing?
People all over the world are seeing different things, but they are all susceptible to the same failings that all of us are susceptible to. They are
not seeing nothing - they are seeing mundane objects, and because of these failings, they misinterpret what they are seeing.

Or second best - none of them understand what they're seeing?
Is this accurate?
Basically, yes!
The objects that are being reported as UFOs might well be easy to identify due to their characteristics if an observer is reasonably experienced, but
throw in a red herring (optical illusion), and all of a sudden what they are seeing makes no sense. When there is a lack of visual cues/information,
our brains try to "fill in the gaps" with what has worked in the past, on the ground, and in familiar situations, but it usually does not work when
applied to the types of situation where UFOs are observed - the result is that we see optical illusions.
To put it another way, we do not see reality. We do see our brain's (often flawed) interpretation of reality.
In a nut shell, all UFO sightings can be explained by the way our brains work (and the fact that there are probably at least a few undiscovered
atmospheric phenomena), although I have only touched on a few aspects - there is so much more to it... however, we can not say with 100% certainty
that aliens have not visited us at some time (or may be even still visiting us), but the complete lack of any hard physical evidence (and the
difficulties involved with breaking the light speed barrier in order to get here, not to mention how "perfect" the conditions need to be in order for
an advanced civilization to evolve) make this a
much more unlikely possibility than the previous possibility I suggested.
Yes, some UFO sightings might be government "black projects" (or even "unique/difficult to identify civilian flying contraptions"), but I seriously
doubt that military tech is quite as advanced as some on here would have us believe, and let's not forget that it suits the military very well to keep
people (especially perceived enemies) guessing, so it would not surprise me that they encourage (in subtle ways) rampant speculation.
Apologies for the long reply, but I would find it very hard to fully explain these concepts in less words than I have used here. Hopefully you have
understood, but if there are any points you'd like me to clarify, please don't hesitate to ask.
