Bob Lazar has repeatedly claimed that he holds a master's degree in physics from MIT and a master's degree in electronic technology from Caltech, but he does not appear in any student records at all.

This would be the biggest news story in history, and yet we have no idea where or when this happened, or any evidence other than a YouTube video where a man who seems to be a proven fabricator states it without any proof or details!

Extraordinary claims need extraordinary proof. "Bob Lazar said something on YouTube" is not any sort of proof at all.

I don't really understand why you believe this, to be honest.
