Traveling across such huge distances requires a gigantonormous (probably not a word) amount of energy. You wouldn't set out at random. You would (as we do) send out probes, much more cost-effective, no matter how advanced you are.
If they worked out something beyond current physics, and don't know about probes...
Zero point energy, free energy, anti gravity.
All of this we dont fully understand, well atleast publically..
remember that our technology is a mere 200 years old.
Imagine a civilization that is 1000 years more advanced.
Had you told the cavemen back in the day that they could fly by building an aircraft they have laughed you right in the face.
Why? Because they had no level of technology at all.
And they weren't as developed as we are.
Why send out probes when you can have crafts capable of doing incredible speeds that could visit planet after planet in no time.
probes sounds like a cavemen way of exploring planets.
...why bother with skulking in dark corners, only appearing to poor drunk American hicks every now and then? They could just come and do as they please.
But it isn't rednecks or hill billies that report ufos... this is the problem..
they are generals, military people, nasa employees.
Highest ranking person that has reported a ufo was an american president!
With that technology, they would also have colonized a bunch of planets, and we would've noticed something by now; Fermi pardox.
Who says they would. Would humans just start colonize another planet with intelligent life? life which is still highly primitive.
Spy and take samples of intelligent life? Of course not, isn't that kind of a hostile act? I presume we'd try and make contact.
Yes, and it came from the same place as a little green man. Someone imagined him, and now he's rather well known
Silly joke, doesn't really work 100%, but what the hell.
What place? Think for a moment instead of making irrelevant jokes.
I'm guessing they saw something that they couldn't explain any other way, and have accepted that it was a UFO. Doesn't really make it a UFO.
Some claim to have seen saucers in hangars, how is that a ufo still? watch the video, you might change your stance radically.
Reminded me of this, not connected really, but pretty cool. Saw an article about it a few weeks ago, would like to see it:
