Fascinating discussion here, have to put my 2 cents in along with everybody else.
Just happen to have some information going back to 1952, its called the year of UFO's.
This was the year the greatest number of UFO sightings received by the U.S. Air
technical intelligence Command was recorded in 1952: 1,501. Early in March 1952, with increased numbers of sightings, in the U.S. Air force decided to create a separate organization called Project Blue Book. During that year of intense UFO activity, the sightings were diverse and many. In 1966 Gerald R Ford, then a congressman from Michigan, was credited with calling for another federal investigation of UFO"s.
At the conclusion of this study,the Condon report was issued. Among other things,
it said that " nothing has come from the study of UFO"s in the past 21 years that has added to scientific knowledge...that further extensive study of UFO's probably cannot
be justified in the expectation that science will be advanced thereby".
This ended the official involvement of the U.S. government in the study of UFO"s and
and in addition tended to cool public curiosity. It did not, however, end the UFO controversy, nor was it the end of UFO sightings. Interest in UFO's seemed to rise and fall along with waves of sightings. Outstanding were the years of 1973 and 1974, when UFO"s were observed. With the arrival of the 1980"s , reports were again in the news.
Question is what have scientists and other experts concluded in more recent years?
Here we are again discussing UFO sightings, seems to be a on going thing.
Science has told us just 500 years ago the earth was flat, that some people had to disprove the myth by sailing the edge of the earth. And, they did not fall of.
My point is not to be taken in "See to it that no one makes a prey of you by philosophy
and empty deceit according to human tradition, and according to elemental spirits of the universe". A very famous writer once wrote those words, I try not to be taken in by philosophy's of others. For instance, check on line about a society called "The Flat earth society really exists. Called them to see if they were for real, believing in this day and age that the earth was FLAT. These collage educated men, think like this, and they will not budge on how they think. Any way, Happy Hovering to you.
