When you know humans lack the sensors to perceive ~98% of the mass in the universe (dark matter) — you know you don’t know anything.
You’re less than a speck, on a planet that is a tiny particle of dust relative to a nebula, what to speak of a galaxy, what to speak of the universe.
And those make up the part we can see... and they are ~2% of the universe.
We don’t understand dimensions and quantum entanglement.
We also don’t understand how time works in all localities and dimensions.
Yet when presented with video evidence of technology beyond our understanding of physics, you START with a macro-statement that it can’t be from outside earth.
These postulations about the limitations of ‘life’ are more absurd than a blind man describing an elephant.
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.
