Interesting how we choose to anthropomorphisize other life forms, judging their behaviors with a human paradigm. Because, of course, the way humans think is the way every other "intelligent" life form in the universe would happen to think too.
Look... its not anthropomorphizing. Its intelligence and understanding.
ANY creature from any planet that is capable of building interstellar craft STILL EVOLVED, under the exact same selection pressures that drove the development of our intelligence. (i.e. for the same advantages in survival )
I don't care what fantasy of other life form you want to postulate... they eat, they excrete, they reproduce ( otherwise no evolution ) and they live or die on RESOURCE MANAGEMENT.
This means that resources have value... and they really can't fly to other planets without massive investments in resources. ( and don't give me your wild fantasies of "hyperspace" et al. PHYSICS is not mutable. )
Its gonna cost them...
And they are going to do that for WHAT reasonable purpose? Because, really, if they are evolved, and intelligent, and capable of the science and manufacturing involved, then they HAVE to have REASON.
So, really... why fly here? To "study us"? how much easier would it be to study us if they said hello?
Your "belief system" is to dismiss Every actual realistic consideration involved with the wave of your hand mumbling about how we can not possibly fathom ALIEN intentions....
But that is precisely the same meritless 'argument' that excuses the immoral acts of a imagined GOD by saying 'his ways are mysterious.'
See how UFO believers are identical to any other religion?
You all just want to pretend that there is a smarter, wiser, more powerful force in the universe... And the "technology" you imagine to ascribe to these 'aliens' is no different than the 'powers' ascribed to Gods or the supernatural. You make them up as needed to evade the need for proof.
But all of that aside... regardless of the stupidity of mistaking fantasy for reality in excusing the ridiculously stupid "actions" of these aliens...
The fact still stands that there is not one iota of un-ambiguous evidence for their existence... and TONS of ambiguous, out of focus, and faked hubcap, and "recovered memory" evidence...
And, sorry, but to anyone who actually Thinks, this is precisely the pattern of evidence you get when Every honestly obtained piece of evidence that is clear and in focus and unambiguous reveals that there is not an alien spaceship.
When all that is left is the crap that proves nothing... what you have is folks IMAGINING they see something in the crap.
