I think that it is very safe to say that UFO's do exist. Mainly due to the fact that UFO's are any unidentified flying object. However, are UFO's evidence of aliens from another planet. Well, that remains to be seen. The first UFO sourced and recorded sighting was in the year 329BC by Alexander The Great. I am one who believes that we are not alone, and just like with the Drake Constant that postulate the probability of Life and civilizations in a galaxy, there has to somewhere out in deep space there be another planet that has some form of intelligent life on it. That life form could be more intelligent then ours or, maybe even not near our intelligence.
One of the UFO cases that has always held my interest is the one known as THE BATTLE FOR LOS ANGELES, back in Feb. 1942. That case like many other cases to the best of my knowledge, has never been solved. The following link will take you to a investigative news story being broadcasted about the incident. The report was broadcasted on the 25 years anniversary of the Battle of Los Angeles. Click on the link and you can make up your own mind as to if it was a real UFO or was it a weather balloon as the government insist it was to this very day..
When you watch this video, try to remember anything in the air is a weather balloon to the government. The government said that, the Roswell Incident was also a weather balloon. The Roswell incident didn't take place until five years after the Los Angeles UFO incident and the government still insist it was a weather balloon ONLY after the U.S. Air Force had already said a UFO had crashed. Here is the link to that story and you can make up your own mind on that story too
I strongly suggest that if UFO research is your interest, You really should take a look at the Battle for Los Angeles video and read the article on the Roswell Incident. Lets just say that the LA incident was a weather balloon, Do you really think that the army and air force could Not shoot down a simple weather balloon? I will leave it up to you to decide for yourself !!
