As well as figuring out whether Buzz went to the moon or not with the science and technology of that time, it's also much more clearer to note his body language and the body language of those who also were purported to have been.
This isn't a case of globe v flat Earth arguments among ourselves, it's literally about using your own perceptive mind and actually applying simple logic to the situation.
Simply arguing for Aldrin's case for no other reason than to keep the space exploit ruse alive is pointless if it's been done by simple unconditional acceptance that he did what we were told he did, as well as others.
I'm quite sure that most, if not all of you have watched the body language of people, even friends and acquaintances, then walked away with a pretty good idea that they are telling you the truth or basically spinning lies.
Buzz Aldrin shows; time and time again that he's having extreme difficulty keeping his part in shenanigans at bay. It shows on his face and in his speech, plus his body language as a whole.
All three of those so called astronauts, Armstrong, Aldrin and Collins, when displayed to the media in those days, showed a variation of all kinds of emotions, from guilt to fear, to shame and duress, etc.
Armstrong showed the greatest emotions, followed by Aldrin, then Collins, in that order.
Although this does not constitute absolute concrete proof, let me explain something.
If these 3 people were being questioned for a big crime and acted the way they did, they would be kept in custody for the maximum length of time for questioning further -plus, they would be under surveillance if they were allowed to go.
It's fine that people argue the case for it happening, but it's not telling the whole story, whatever that real story is.
It can be argued in a number of ways by people. It can be argued that they show emotion because they are hiding the fact that aliens were on the moon, or they saw structures on the moon, or any other pile of absolute bull shit, and the issue is about who is sensible, logical, clear minded or gullible enough to take any story as is said.
My guess is, if you put any so called astronaut under a controlled lie detector test, fully tested by sceptics as well as so called scientists, my guess is, the lie detectors would not only show up lies but they would overload and blow up due to the severity of them.

It's easy to go along with all kinds of brainwashing techniques as well, from hypnosis to LSD or some other mind altering drug to make them believe they did what they tell us they did.
The rabbit hole is probably very deep where this stuff is concerned and all we can do is guess. Nobody can factually state it happened or not, because the simple truth is, none of us can physically prove anything. All we can do is use a logical mind.
The problem with this is, people are different and arrogant, who believe their mind is logical, yet can come to totally different conclusions. There's also logical liars that can make absurdities appear logical to the gullible who actually believe they are logical.
It's like a game of chess in it's latter stages where checkmate looks unlikely for either side and stalemate offers a better outcome, yet both sides still believe that the other will make the error and allow the winning move to take place.
