They don't bring up that stuff because it is all hogwash.
Here is a very nice collection of pictures and vids of earth. Some have been around for decades and none have been proven to be fake.
Have a peek: http://planetary.org/explore/space-topics/earth/pics-of-earth-by-planetary-spacecraft.html
Well those pics do look fake though... What validates their authenticity? The source? I guess i can tell they are real because they look so fake...
They "look fake", (whatever that means), to you because they prove you wrong. Better to believe they are fake with no proof whatsoever, than accept their authenticity. Remember, these pictures have been available for years and even decades and not one has been proven to be fake. Not one. Ever. Not fake. In other words, they are real.
