Here's a loong video but worth watching. It's incredibly interesting. Not saying I necessarily believe the guy, but I mean who knows. Impossible to make any conclusions really.
I fell down the Bob Lazar rabbit hole before; he is interesting but I don't believe a word he says. Add to that, Jeremy Corbin, with whom he was being interviewed by Rogan, is also a grifter who claims to be a skeptic who explores everything objectively but he almost instantly jumps to aliens/UFOs at the earliest opportunity. He is not some earnest researcher looking to debunk things and only accepts aliens when no other explanation is warranted - he jumps to aliens whenever he sees dollar signs.
Bob on the other hand is far more interesting. I think he is a fraud, but he has persisted in his lies for so long that his story is fascinating, regardless of whether he is telling the truth. There is a long post on imgur/reddit I am trying to find that outlines some of the evidence against Bob. Just a note - a lot of the info against Bob comes from the late, great Stanton Friedman, who was everything Bob and Jeremy claim to be - a real nuclear physicist who applied a critical eye to the study of UFOs not simply to debunk but to bring legitimacy to the study of UFOs. Anyway, the evidence against Bob includes that there is no record he ever attended MIT or Cal Tech, that he was never clear on when he graduated from either place, and that he couldn't name one professor or fellow student at either university (when asked by Friedman to name any professor/instructor Bob had at MIT or Cal Tech, the only professor he did name when asked was a professor at Pierce Community College, the only school in which there is a record that Bob attended). Bob claims that the government wiped his academic records but also cannot point one piece of real evidence - a diploma, a term paper, an exam, an eyewitness, a picture of himself on campus, a textbook - that would show he attended either MIT or Cal Tech. In fact, the records that exist show that Bob was attending Pierce Community on the West Coast of the US in California at the same time he claimed to attend MIT on the East Coast in Boston. Bob has never explained how he was capable of attending both institutions at the same time or why an MIT student would ever need to attend a community college. Stanton Friedman also found his high school records and claims that Bob was a middling to subpar student who would not have been offered acceptance into either MIT or Cal Tech.
Bob also claims that the ship's fuel was Element 115, now known as Moscovium, which his proponents will tell you wasn't synthesized until after Bob came forward with his story - thus, Bob knew the element existed before everyone. Bob knew about Element 115 before it was named or even on the periodic table. That's crazy, right? Well, its bullshit - I don't remember exactly the terms, but chemists have known about the potential existence of things like Element 115 for hundreds of years, they just couldn't synthesize it and thus it wasn't named. I believe on periodic tables during Bob's time there were even blank spaces left on many periodic tables in anticipation of things like Moscovium, element 115, being artificially created.
Bob also claims to have never made a cent off of his stories when there is plenty of evidence that he profited, including a book, speaking tours, selling his story to multiple movie studios, selling hand drawn pictures through social media and even designing toys made to look like the craft he claimed to have worked on. The guy is the archetype grifter claiming to never sell a thing when he was probably making money off his story from day 1.
He also claimed to have worked as a physicist at Los Alamos before working at Area 51, but the records show he was instead a contracted technician working a job that directly linked to the degree he obtained from Pierce Community College. After working at Los Alamos he himself even admits that he went and started another business, a 1 hour photo development store. And finally, while supposedly working at Area 51, he also owned and operated a brothel and was in severe financial hardship.
So, for their super secretive program that only a handful of people EVER witnessed (I think Bob claimed only about 20 people worked on the program), by Bob's own story, the US government hired an individual who had not been working in any related scientific field for half a decade, didn't have a PhD, and didn't have any published papers. In the best case scenario, Bob has to explain why the US government hired him instead of any of the millions of better qualified candidates out there. He doesn't explain any of this, and simply admits he wasn't necessarily qualified but claims that he was kind of an outside the box thinker. In the worst case scenario, which I believe, Bob has to explain why the US government would ever hire a community college graduate with extreme, extreme security risks (owns brothel, in dire financial situation - basically giving super secret information to a guy who is more likely than anyone to sell that info to the press).
Bob is interesting to me because his lying is at pathological level at this point, but also because it shows how a guy with a basic understanding of physics and a keen interest in science fiction can convince people he is some sort of super genius who worked on the most top secret program ever. I admit that when you hear him speak about the craft, how it flew, I cannot debunk it, in part, because I am so scientifically illiterate. I think what Bob shows is how so many, including myself, can barely understand scientific concepts beyond a rudimentary level and when someone speaks to complicated subjects with an air of authority people have trouble separating the fact from the fiction. That being said, I think people are better at detecting other lapses in logic in another person's story that doesn't involve technical language and relatively foreign concepts and Bob's story has enough of those if you look closely enough.
