the ufo that allegedly crashed in tha late 50's in the US was in Roswell New Mexico on a cattle ranch..area 51 (in nevada desert) is where the military supposedly keeps the ufo, debris from the crash, and as eyewitnesses to the crashsite/cleanup report, the alien bodies
there are signs surrounding area 51 that trespassers will be shot very secretive hush hush surrounds the place and there is all sorts of conjecture as to what actually goes on there.
the military to this day states that what actually crashed in roswell was a weather balloon. skeptics to this theory believe this to be one of the biggest military coverups in the US. there is also a military file called "project blue-book" which deals with alien/ufo sightings. has been partially released to the public but lots of holes and contradictory statements. this further leads to military coverup.
not saying i believe one way or the other, just interesting to read about/watch documentaries about.
i would personally have to see it with my own eyes to belive any of it, ghosts included (although have had a fair share of creepy experiences with ghosts/paranormal over the years, just never actually SAW anything and am not one to jump to conclusions..but that is a topic for another thread).
Probally the same conspiracy theories that said the Jews did 911. Conspiracy theories are a joke really...
And I agree, seeing is believing.
Heres a picture that you might find interesting, my sister took this photo of a sunset while walking the dog.. and only realized until she got home what she had taken a photo of..
Why are all UFO pictures blurry?
