Jo Rogan did a podcast with Bob lazar. It’s on you tube and can be found easily.
We do have craft from wherever they are from. We are attempting to reverse engineer them.
The other day Joe had on 2 guys who know Bob very well. One is a film maker , the other a reporter. After 31 years Bobs story has remained consistent and he has yet to make a dime from any of this.
More than likely he is telling the truth. No idea if these craft are from a different dimension or a different star system.
