If these folks from “outside the Earth” are so advanced that they could cover the lightyears to get here, you would think that they could actually avoid being SEEN by us, until they are ready to reveal themselves?
Or, to do think that they are smart enough to get here, but, so incompetent that they can’t actually cover their own tracks? They can’t hypnotize folks so that we can’t uncover their mental tampering, while, we can put people in a sleep mode to give them a colonoscopy, and, they can’t remember anything about what happened?
Do you mean that they can travel lightyears, but, once they get here, their craft is so poor they crash land when they get here?
I think that the poor observing skills of most humans is the best explanation. I’ve been an amateur astronomer for 50+ years, and, have yet to see anything that I couldn’t point my binos or a telescope towards and identify it, if I couldn’t tell naked eye.
You must begin your analysis from the rational standpoint, which is that you're analyzing their actions from a place of complete ignorance. You don't know their values or motives or what perspective on reality they're evaluating things from.
And 'observing skills' of Navy pilots with multiple instrument readings show impossible speeds and maneuvers in this encounter from an excellent interview with Commander David Fravor. You may find it entertaining. https://youtu.be/Eco2s3-0zsQ
