There were a lot of shortcomings in the Blue Book project from the beginning. It was under staffed and under funded, and the purpose of the project has been questioned, considering some of the absurd conclusions they reached. And even with their enthusiastic attempt to provide a rational explanation to anything that came their way, they still ended up with around 700 or so unsolved reports. I'm not saying that proves anything, just that they didn't do their job well.
And after the project was shut down, its head scientist went on to become a leading UFO researcher.
The vast majority haven't been investigated. As for the cases apparently closed by Blue Book, their explanations vary far and wide from what was actually reported. Yes, a lot of sightings are satellites and aircraft and even the reflection of lightbulbs on windows. But the explanations provided by Blue Book aren't the final verdict, and I would go as far to say most of their conclusions should be thrown out.
You're absolutely right. However, it is enough to suggest that there's something being seen and captured on film that doesn't fit conventional explanation. Stating the obvious ftw.
Yours aren't much better. Where's your counter argument? "The government said it was so QED"?
Yes, most sightings probably are rubbish. But it's not like looking for a silver frisbee in a sea of bull****. You've got to realise that at the beginning, before the media jumped all over it, that there were honest sightings of unexplained stuff in the sky, before "flying saucer" and "roswell" polluted the vernacular. Now, however, people either have that notion locked in their heads that UFOs must be aliens, or that anyone that even utters the syllables must be a fruitcake.
As for abductions, you need to make the distinction between abductee and contactee. Contactees are those people that say sexy aliens came from outerspace to have sex with them, or tell them they need to save the earth, and so on. All these people are nutbars and should be ignored.
As for the abductees, there's undoubtably an issue there. I'm not saying aliens actually abduct people - it's something that really doesn't make sense. But abductees are usually the people that become deepy affected by what they say happens to them. They go to sleep feeling fine, everything normal, and wake up having experienced something truely horrifying. A nightmare, by all contemporary standards, that they can't forget. Others simply realise they've 'lost' some time, and either through hypnosis or flashbacks they recount the ordeal. Now what mechanism could have an ordinary person to to sleep and wake up scared of the world?
Sightings of objects all shapes and sizes have been reported on all continents for at least the last sixty years. Abduction claims have been made on all continents, although only in the last forty or so years.
But think about this - if UFOs are piloted craft, and they've been doing this for sixty years without just coming down and saying "sup" they probably don't want to be seen. So if they were going to pick up a cow or a person or a shopping trolley, they'd probably rather do it in a less populated area. In my recollection there have been very few, if any, reports of abductions in city areas. Not to say there haven't been sightings. Lots of sightings in city areas. I guess the aliens like the pretty lights.
Final notes:
I consider that UFOs and abduction phenomena are two seperate issues.
Not all witnesses or abductees are "believers" before their sighting/probing.
