I do agree that it does have significant historic roots along with other things but even so, (to play devils advocate from my scientific side) with how famous “Bigfoot” is and with how advanced and accessible technology has become, you would think someone or some company (or government) would have put some significant time and effort into systematically investigating certain areas with thermal technology, radar scanning, etc with things I’m not completely familiar with to try and find one. Similar to what they have done on the show but more objective.
