So UFO's and aliens... what's the deal?

And then one of them pulled this video link shot by Meier long ago on 8mm where, according to them it is without question evidence of real aliens because somewhere around 8m 20s there he filmed a saucer going behind a mountain and that, my friend, could not be faked and others agreed. OK, so I looked the video

I looked at that spot and saw no point where the ship "definitively" went behind the mountain.
It could have at one point. Or, more likely, there were other issues.... 8mm film is crappy for trying to capture details. And, the film tech of the day, at least for consumer film, gave people a medium with horrible dynamic range. The ship and the mountain had the same tonal value, as far as the film was concerned, and just literally became one "object" being recorded.
Do that today on modern 35mm stock and you will see absolute detail and tonal separation between the "ship" and the mountain.

Not to mention, the way the alleged ship is flying makes it look like it was designed and flown by a bunch of incompetent buffoons.
