I do find Bob Lazar's accounts very credible. One main reason was because he wasn't doing it for the money, and his explanations sounded like truth more then millions of lies. The naval paycheck is the interesting evidence here.
Historically though, he was the whistleblower on Area 51's existence. Which has finally been publicly shared by the gov that it exists after sooo much lying and denial by the government.
I do like the theoritical explainations and claims of the reverse engineering he did, and it makes sense to me as a physicist and engineer. I don't dismiss "new" ideas/theories so easily as the average person does. Even if a hint of some truth is in his claims, then that's a much greater "awakening" of knowledge then what modern science has going for it with their focus on making as much money as possible with monthly journals.
