I'm guessing you are referring to David Fravor[1] when you say "the one about UFO's".
I dunno. I'm a skeptic by nature (not just of UFO's, etc., but of almost everything) and I watched that episode and thought it was good. Fravor seemed like a sharp, knowledgeable, down-to-earth guy who was simply stating what he experienced... and went to great lengths to be clear that he wasn't necessarily positing that what he saw was caused by Little Green Men from Mars.
FWIW, I don't believe that intelligent aliens are visiting Earth, although I do believe that it's likely that there (is|was|will be) intelligent life elsewhere in our universe at some point in time. Given that bias, I didn't find anything particularly objectionable in the Fravor episode. But perspectives vary, of course...
It's ok man, it's not a religion. You can skip those if you don't like them. He's also had James Gosling, Don Knuth (x2), James Keller (x2), Brian Kernighan and a bunch of other legends.
You are right of course, but this whole phenomenon really rubs me the wrong way. There is a whole host of podcasts now that provide a large audience to borderline crackpots. I believe it actually pushes people who are maybe otherwise quite intelligent to adopt such theories, because of the large audience that can now be reached with such stuff. Another good example is Avi Loeb and the Alien-Omuamua theory, explained quite well here: https://www.reddit.com/r/slatestarcodex/comments/o1dhlf/comm...
