Those videos and stories about Mexican flying beings are interesting. They are kinda creepy, actually. There's probably some logical explanation, though.
Yeah they moved the contents of Area 51 down to Mexico.
I wonder what a video of UFO's or other weird phenomena would need for people to agree that it was real?
I suspect that no matter how much video evidence was provided, someone somewhere would argue that it was fake.
"Fake until proven real."
Ever heard of that stance? Well, if you haven't, there it is.
Also: You are right about one thing - that there will always be someone that argues something is fake despite collosal amounts of evidence. Look at creationists for a perfect example.
