UFOs - proof?

When it comes to the question of whether we're alone in the universe, I find myself generally not terribly convinced either way. So; on the one hand, despite the size of the universe, I can't help thinking that the chances of all the necessary circumstances for life to evolve happening anywhere other than here are so absolutely tiny that it must be virtually impossible that there would be life out there. And then in a stunning 180 degree turn, I similarly think, based largely on the same logic, that the universe is so vastly enormous that it seems inconceivable that life of some form WOULDN'T have evolved on other planets, either inferior or superior to our own. Then I basically come to the conclusion that these are probably matters which are far too enormous for me to have any reasonable grasp of and I go and put the kettle on.

So now that I've made that all clear(!), have a look at this video which I found last night while doing my usual random wanderings around the internet. I'm not one for conspiracy theories (I was gonna put this on the CT forum but this looks a bit too convincing to sit there with all the theorised "moon landing was fake" and "9/11 was an inside job" threads - no offence guys), nor am I one to throw stuff like this around thoughtlessly...but this video, I gotta say, makes an unnervingly strong case, not only for the idea that there's life out there, but that it's a lot closer to us than we might care to imagine, possibly even already here. And yes, I know I already sound like a total crank - but watch the video and see if you can convincingly argue otherwise, and give rational explanations for every single thing that you see. If you can I'll be very pleased. Particularly with the frankly bizarre interrupted radio interview that takes up the last few minutes of the video.
