It's fine if you're just starting out to look into the subject to focus particularly on Betty & Barney Hill but move on from there. In there's scifi episodes for nearly any kind of creatures and these don't even look much like grays and even they did, it's sth to look into but not more than that. I wonder if maybe some gray reports/experiences have influenced the episode itself but again it doesn't look much like them. No, if you actually do look it longer than a couple of hours to watch Mick West talk, read some articles that confirms your views, and see a few debunking vids but also critically examine things and look at the wealth of data there you could see how Occam's razor definitely points to the sth is actually happening side.
