I don't think anyone here thinks they're "actors"... liars yes, but even scientists can lie.
Take for example, Nasa.
Proof of these lies, please... merely saying they CAN lie is not proof of a lie.
I suggest you browse the forums for that data.
If any government wishes to order a court summons for voicing this opinion, I suggest they print it on flat paper.
That 'data' you refer to is some people on the internet saying that astronauts are clearly in water or it's all clearly cgi, or there's clearly a harness holding them up yet when I see these videos and photos they refer to I don't see any of that... Not even remotely. The only thing I've seen is the claim of cgi 'glitches' which are just lossy compression videos and photos.
One photo in particular where flat earthers claimed nasa photoshopped in a moon just so happened to have been edited which was explicitly stated on the nasa website that they just added some brightness to make the photo a little clearer and pleasing... Yet you have people like Tom creaming that it is obvious that they photoshopped in a moon (despite that same website having the original photo as well as the edited one). Another photo where nasa supposedly photoshopped in a moon just so happens to be an edited photo from the internet using a NASA photo as the source, so it wasn't even nasa, just trolls.
You have people here claiming astronauts are held up by cables yet point to videos where there are no cables. You get people here pointing to 'bubbles flying about during space walks' as if it's impossible for little bits to be floating around in space. People here claim that zero gravity is just on a plane diving down to earth, as if they could make a 50 minute video exploring the ISS with no cuts or transitions to the video on a <1 minute plane dive. Heck there are even people that outright deny the ISS exists despite the fact you can see it with your own eyes. People here claim the moon landings are faked just because they don't trust nasa, not because there's any actual evidence of fakery. Even the Tesla car that got launched into space recently people claimed fake because "you can see the studio they were filming in seconds before the cgi space background appears", which couldn't possibly have been the car sitting inside the rocket, right? NASA training their astronauts in pools is also not evidence of fakery either, in case anyone throws that in. Let's not forget how people also think that Curiosity is actually on earth, even though no one has ever ventured out to the part of the world they think NASA are filming on with the rover. Funny how no one has come across NASA actually doing that here on earth secretly, despite being out in the open.
Anyway you get my point. You have every right to not trust NASA and every right to be sceptical of all other space agencies if you want but your lack of trust is not equal to evidence that NASA lie. This is why above I quoted someone and said "allegedly". because all these claims that NASA are liars are just all opinion based, not factual. I'd suggest before claiming anyone are liars, claim with hard evidence otherwise that claim makes you the liar. Flat earthers most certainly do have an agenda, they NEED NASA to be fake if they're to believe the earth is flat. wanting NASA to be fake doesn't make them fake though.
Of all my time here the only people I've seen giving misinformation are flat earthers.
