Mexicans are known for spending their time faking this kind of things..
On one of the videos I can see a reflection of a human face, overlayed on top of the actual "video" tell me why...! Perhaps they were pointing the camera to a reflective surface to accomplish the illusion of those foo fighters on the video (think Its around minute 26 - 28 of the video if I remember well).
Also, you can not by any means see heat from a normal picture

those are just image filters they applied, but is no way heat .. telling you, I work on image manipulation all friggin' day!.
Many of the photographs he shown are fake as well, and pretty easy to fake. Even the one from CHILE is a fake, is no way an alien its just a dog.
Another thing: he keeps on repeating "it would be too expensive to make such a big puppet" Sure ? with about 800 bucks you can make a real human replica with all you need to make it look real. How much would you spend on an alien? well perhaps even less money, given they are skinnier. (lol).
Seriously The only thing that impresses me are some of the crop circles
I can only explain them, if it was faked.. to be an overlay on top of the video. That is possible, but... well, how can you prove me that they really existed? that they were there? You should have 100 photographs of you at it then!, show them. if not, its still easy to fake. You show a video, well you can fake a video.
But you show me 100 pictures of something and I might believe it. (even so, you can still fake 100 pictures, but on more than one you'll commit some mistake and thats where you get to know its all a setup)..
I liked the shaded crop circles... Way too much, but thats the only thing I liked of the video, everything else is really easy to fake. Most of all coming from some mexicans that do this for money (seriously, and got nothing about mexicans though... but some people over there makes this fakes for selling them).
There was this video of an ufo passing by some buildings some time ago, everyone thought it was real but if you analyze the video, its just an overlay...
