The first video was on a couple of recent threads.
Not sure about the second one, but in that one, the person speaking states that in the early 1990s, a fleet of thousands of flying saucers flying over Mexico was driven back to wherever they issued from (presumably inner earth )by US, Canadian and other air force teams.
That sounds like a very dubious statement to me. Is there any proof of such an event? There would surely have been lots of eyewitnesses!
He also talks about the gov rethinking how gravity is created, and that sounds like it could be true, judging from recent revelations on that subject.
