I mainly wanted to point out the issues in that one particular video. I'm not a fan of NASA.
In your reply you've actually done something flat earthers usually do; you've shot the messenger (the forbes, foxnews, quora links) and added a handful of new videos and new arguments.
Do you think the explanation for how NASA lost the technology to go to the moon is not credible or did you not read them?
Van Allen radiation belt explained by Van Allen himself:-

Since you posted this it seems you did not see my two links explaining why the lunar lander looked like that?
Pararell shadows can appear to look not pararell depending on perspective, see:-
The one particular image that Sibrel analyses is a bit trickier since the shadow behind the rock is not very long. I do believe both shadows do however point to the same vanishing point.
Here's an example of a similar image. See the shadows on the rocks on the right (and left) that appear to point to the sides instead of the same direction as the shadow of the men.
If there were multiple light souces there would be multiple shadows (for the same object)
In the part which claims to show the astronauts faking the distance to the earth in "A Funny Thing Happened on the Way to the Moon", (which from some reason has an image from the Hollywood movie Capricorn 1 as it's thumbnail) at 33:28-> I believe the documentary is leading and misinterpreting. (Transcript). I could go through it bit by bit and explain but that would take too long to document.
Some analysis from: This conspiracy is a conspiracy!
As far as Bart's much ballyhooed "never-seen", secret NASA Apollo videotape was neither
"never-seen" nor secret. It was all taped footage from the Apollo 11 CM Westinghouse three-color camera telecasts that were broadcast live on NBC, CBS, ABC, the BBC and every other decent network on the planet back in July of 1969. Many ordinary citizens have documentary videos that show the same broadcasts. The times and dates of those broadcasts have long been a matter of public record and the documentation can be viewed in the NASA Apollo 11 Post Launch Mission Operation Report (Number M-932-69-11.The video was so blurry and fuzzy that Houston had to prompt the characteristically un-talkative Apollo 11 commander, Neil Armstrong to describe what he was pointing the camera at so that NASA could correlate what he was shooting with what he was describing on later tape playbacks. Color TV cameras small enough to fit inside tiny spacecraft cabins were brand new and balky technology back in 1969. Global communications networks could not even synchronize the audio and video signals coming back to Houston from receiving antennas in Australia and Goldstone, California.
The only thing new and weird revealed in Sibrel’s A FUNNY THING HAPPENED ON THE WAY TO THE MOON is his bizarre personal interpretation that the video views of earth were shot through a small hole (template) to give the impression that Apollo 11 was not in low earth orbit. Sibrel insists that none of the Apollo spacecraft ever left low earth orbit because of the “radiation barrier” called the Van Allen Belts. This radiation barrier is greatly exaggerated by all of the “moon hoax” proponents. Sibrel’s misinterpretation of the archival Apollo 11 video results from a combination of Bart's longing to see something awry and his lack of understanding about the Apollo cabin and TV camera configuration.
Sibrel attempts to describe to the viewers of his documentary what is going on inside the darkened Command Module while the crew was attempting to give the TV viewers back the best possible view of earth with the primitive handheld color TV camera carried aboard Apollo 11. The problem with his explanation is basically that he does not know what he is talking about. Sibrel may know a lot about current video editing and production technology, but he does not have expertise about Apollo. In order provide 1969 TV viewers back on earth with the best possible view of our planet from space, it was necessary to eliminate the glaring reflected light and direct sunlight that was streaming into the spacecraft and interfering with the shot. The official Apollo 11 mission documentation from 1969 contains astronaut Michael Collins’ own discussion of these lighting problems and the difficulties he experienced with the window shades in the Apollo spacecraft. Unfortunately for Bart Sibrel, he is obviously unaware of astronaut Mike Collins documented statements. The astronauts shuttered most of the capsule windows with special shades that blocked most of the glaring direct and reflected sunlight coming off of the bright, shiny Lunar Module which was docked in close proximity to the location of the windows.
The earth was then clearly visible out of the other "unblocked" cabin window when the shades were closed. What one actually witnesses in the video are not cutouts or templates passing between the earth and the TV camera, it is the communications headset wiring, arms and body of astronaut Michael Collins as he reaches over to remove the shade blocking one of the spacecraft windows. As soon as the shade is removed, the video shows the cabin immediately illuminating with glaring reflected sunlight. We also see that Collins is the one opening the window shade and that another member of the crew is obviously handling the camera from the vicinity of the foot area of the crew couches. Sibrel expressed the mistaken impression that the hand-held Westinghouse TV camera was hard-mounted to the face of the cabin window. Sibrel, as well as his devoted followers are the victims of misinterpretation and apparent misinformation.
Bart is far from what you would call a space expert (although he does have good TV editing and video production skills). He does not appear to possess an understanding of the basic layout and configuration of the Apollo Command Module or the procedures followed by NASA during the Apollo telecasts. Bart has misinterpreted things that are immediately obvious to anyone who has extensively read Apollo history and documentation or anyone who has ever been inside an Apollo Command Module or accurate mockup.
