Yes and no.
Lots of things have been kept absolutely out of the public eye and even from proper government oversight for decades.
In case of the UFO stuff, lots has come out. But any hard objects and quality photos always get retrieved or destroyed before wide distribution. Dr Stephen Greer has a lot of stuff waiting in the wings for disclosure when the sources can get Congressional Immunity.
Anyway--it will surface. But life will not be the same once it does.
Thx for your kind post.
Right now I see UFOlogy often positioning itself in contrast with the worship of God as our superior being, so until I see verifiable proof that another intelligent being exists, I am extremely skeptical. With the plethora of questionable forms of communication, from tabloids to Jerry Springer, if there was something concrete, someone would have done whatever it took to turn a buck on it by now. Peter Jennings being questionable too, of course!
