Wait, so a video can be used as proof for FET, but it can't be used for RET?
I say let them have that, otherwise the discussion around FET would be over.

As for the videos, they are the main reasons why I have doubts about whether NASA went to the moon in the 60's and 70's - but I'm still not convinced that they didn't and even if it does turn out that the videos are fake, I don't believe that constitutes proof that the entire space program is fake.
For one, if the videos were fake, it is not actually proof that NASA never went to the moon. There are several reasons why the videos may have been faked. I won't elaborate here because I don't have the time, but anyone can look it up.
Secondly, even if NASA really did not go to the moon back then and the videos were faked to convince people of the opposite, there is a motive: the Soviet Union and the space race. Obviously the US government would not want to simply concede defeat against the Soviet Union.
All in all I believe that
if the videos of the moon langing are fake, we are still very very far from proving that every single space mission since then has been faked aswell. Not to mention that no one would "pretend" to put a space station in space when they couldn't really do it, because the damn thing would be (and is) easily visible around the world. Consider that the russian MIR space station was up there for 15 years, and the ISS has been up there for 10 years already and is still under construction. Why would they go to the enormous trouble of faking that?
