Not sure I believe in the hollow earth theory if that's what you're referring to, but it's interesting.
I do believe in unidentified flying objects. Doesn't mean it's extra-terrestrial. It could be in our backgarden with love from the government.
Why is that UFO?s are only visible in US but not in any country? Do you guys really believe in existence of Aliens? If at all they are aliens do they believe that earth is only America?
I agree to you. There are also UFO sightings here in the Philippines but most of them are known to be hot-air balloons and sometimes airplaines or jets. I remember reading that B-2 Bomber is often mistaken as a UFO because of its shape. I haven't seen one so I can't really tell how they looked like.Well, you're wrong. I live in latin america and you can see UFOs everywhere. I actually saw an alien ship at less than a yard away from my head. I know aliens exists, and i know they come to the earth. If you don't believe me, that's another story.
UFO's were actually quite prevalent in Britain and Russia too.
I remember seeing an entire special on History channel covering the UFOs spotted in Russia. Stalin was very interested in them and had a special council track the instances. He ordered them to stop when an adviser pointed out that the sightings eerily coincided with their secret missile tests.
I'm sure that life in some form exists outside this planet. The problem comes in overcoming the difficulties of the vast distance between the planets.
There is also a sad note that Carl Sagan pointed out. Since we haven't been contacted by an alien race, that only leaves a few options.
1. There just isn't any alien life out there.
2. There is alien life, but they never figured out faster-than-light travel.
3. There is alien life, but they killed themselves with warfare before they made the scientific advances necessary for faster-than-light travel.
Number 3 seems to be the most likely. We've seen that most technological advances come with equal gains in killing abilities.
