The outdoor guy Les Stroud “Survivor Man” did a whole series (2 years??) regarding Bigfoot after an odd encounter in Alaska. He approached it with an open mind but lots of scrutiny too - he was always looking for alternate reasons why branches might be broken, tracks, etc.
There are claims that orbs (lights) will be in the area where Bigfoot are (some claim they are interdimensional or something). He was alone in an area said to have a recent Bigfoot siting and he was camping at night.
He said that he saw three red lights that were positioned across the valley at various points in the sky, would float around, etc. He said he watched them for 45 minutes.
After they were gone he realized that it never occurred to him to film them! That is what he does - he has very good quality cameras with him to film himself when he is alone and to put it on TV. He couldn’t explain it, and realizes why would anyone believe his story.
He said something like “Well, believe it or not. And I can’t explain it. And I would like to think after the years of doing these shows and showing you my mistakes, my difficulties and being honest with you in those, that you would believe me when I told you what I saw. But - I also understand why you wouldn’t believe me. I can hardly believe it that I didn’t film them!”
After watching a newscast about this and hearing the young man’s 911 call, it doesn’t sound like he was in shock at all. Sounded like he was trying to recall old movies and what the aliens looked like in them.
Also surprising, he didn’t sound drunk or high.
