It's very easy to disregard someone else's sightings, in part because it is difficult to accurately describe what you have seen in terms that give the same impact as the sighting.

Even videos have a similar problem for a variety of reasons. A video of a lighted object in an otherwise dark sky gives no clues as to the size and motion of the object. The motion could be due to the camera moving, or the object moving. If the camera tracks the object and there are no background objects, you can't see that the object is moving. An average video camera does not pick up background stars well, so there are no reference points. You need a sophisticated night vision setup for that. Also, CG is so good now it is easy to produce very good fakes.

So, before telling an eyewitness they are misinterpreting what they saw, it would be better to ask for additional information. How was the object moving? Where was it in the sky? How did it appear/disappear? Were there other witnesses? etc, etc.

Sure, most UFOs are misinterpretations of objects with conventional explanations, but many are not.

The rectangular sky lanterns offered as an explanation of the diamond shaped UFO were the wrong shape and there was no evidence of a flame at the bottom. Not a good fit.

If you have done your homework you know there are sightings with ground visual, air visual, ground radar, and air radar tracking all on the same object with records and testimony from multiple witnesses/operators. They exist.

Ask to see one. You may be surprised!
