On top of that you have the other contractions such as Ufologists and people who assert they have worked on top secret back engineering of alien craft but who seem definate that they know the Moon has nothing to hide or neither does Nasa.
I know when Bob Lazar, the scientist who alledged worked at Area 51, when interviewed on Coast to Coast stated a couple of interesting things that he believes. He dosen't seem to think people would react too much if the information were to be brought into the public regarding alien technology. And he also seemed sure that there are no Moon structures and artefacts or anything else. it's the same with the Hollow Earth and Moon theory.
I dont know why if they would fake something that they would leave evidence and tell tale signs around for us to discover. Yeah im sure this happens of course all the time when making films with mistakes abound, but would they be careless as to do the same with something so secret and not try and hide them? if they thought stars would be seen i think they would have put them in.
One thing iv thought of and many people seem sure also is that the whole alien contact thing has never happened, stating that if they really were here they would made it public. And they think that all this recovered alien technology and possible back engineering and incorporating into our own is basically a dupe to hide what we have really been working on ourselves.
The problem here is that i would it be a big deal to admit we are designing things ourselves and have to go to lengths to disinform people with claims that we are working with aliens.
Who to believe?
