Is this proof of aliens/bigfoot/demon/ghost?

It seems detailed and has comparisons.

No. That does not constitute compelling evidence for bigfoot (or anything else).

I like the idea that could be a viable population of a large hominid/ape (other than humans) in the North American woods, but it has no credibility in mainstream science. This is because of a total lack of hard evidence (if that were to change scientists would be enormously excited and you'd be hearing about it on national news, not just through youtube clips and cryptozoology websites).
