There are a number of behind the scenes films of the making of 2001. Kubrick's' cameras are well documented. As was the production.
I watched the moon landings live. It was not faked.
If you look at the moon scenes in 2001, you can see its in full gravity. The Appolo films show low gravity and that was impossible to fake.
I don't know how this got started, but it's a distraction at best, and discredits anything else you might be right on.
