Who is this "we" that "knows" film was shot in the Mojave desert? I've looked at all of the so-called "proof" of fakery, and none of it stands up to critical examination. As a professional photographer and amateur astronomer, I can't help but laugh at some of the "proof" that photographs were faked that has been put out -- all of these show a complete misunderstanding of basic principles of physics, light, photography, etc. None of the "proof" of a conspiracy, when examined by someone with knowledge about science, stands up to scrutiny.
Let me ask you: why are you so eager to believe in a vast conspiracy that would have to be kept quiet by hundreds of thousands of people and would serve no useful purpose? We've had our failures in space, spectacular ones, and they've always been in plain view.
Besides, don't you think the Russians -- who were in a race to the moon with the US at the time, and for whom the whole "fakery" was supposedly done -- would have cried foul immediately if they thought the US had faked the landings? They never did -- they only congratulated the US on their accomplishment.
There is no "proof" that the moon landings were faked. There is a TON of proof that they were real. Your conspiracy idea is not backed up by evidence.
