Why people always believe Aliens must crash landing to earth, when we found it, or only we can find it?
They cannot come here, and waving their hand to us?
They cannot send probe just like we human kind send voyager to Titan?
They must land in US, so that secret can be kept?

What is the odd chance of alien spaceship landed in US alone, and not other countries so that secret can be kept by US gov/NASA?

Aliens can a worm type living underneath of Titan ocean, Aliens also can be microscopic organism that living underground. Aliens can also have 8 eyes so that can easily see all the dimension, up down, back, and forth without turning the head.
I had difficulty believe Alien is the same type/structure of human kind, as what many speculate.

Maybe announce that we human kind actually is Aliens. Remember there is no human kind before the dinasour ages, so we could be the Aliens concur this earth.

for me, the only news that I anticipate from Voyager 1 is that is there any life out there?

I also wonder how will any life-form be able to play the record it is carrying?

friend... infact, I do not like the word ALIEN.. it sounds like we human are the reference point of the universe. As a matter of fact, they are just like us... satient beings.... living organism.

a guy once asked an astrobiologist "what makes you think aliens need oxygen and need water to survive?"

he answered "well, I dont really know, like physics and astrophysics, IF the laws of physics is valid on earth and our solar system, I would  ASSUME it is valid as where too "
