We already know that the UK and US have been doing alot of research about it secretly.
show us the evidence.
And its known that the US do know something to, they are just to "greedy" to share it with anybody else.
this isn't the cold war. if we had the stuff we would use it to our own advantage. we wouldn't hide it from ourselves.
of course we wouldn't let anyone else have it.
some info if some would be interested:
Kecksburg UFO Crash
a few videos with Dan Aykroyd
oh shoot me. google video?
For all we know the aliens could be fleeing climate change on their home planet and scouting the universe for other suitable worlds, and any technology we have would be useless, then it could just be...y'know...CUCKOO CUCKOO.
let me make it clear that any interstellar drives are certainly not as clean as people seem to like to believe.
in fact they're probably worse than most other things (matter-matter annihilation? can you say widespread cancer.)
I believe in alien life. I dont believe they are here on earth, far less that they would get 1/2 way across the visible universe only to crash laughably on our planet.
