The hoax proponent will simply declare that the reality of the moon landings is the extraordinary claim, and requires extraordinary evidence...
People who say NASA sent men to the Moon have extraordinary (and extensive) evidence for this claim. Hoax believers may ignore this evidence or deny it, but it still exists.
The hoax believers say that thousands of people participated in a hoax that worked well enough to fool scientists and other space agencies all over the world. They say that thousands of faked photographs were created and that several days' worth of footage were shot in a studio that looked like the Moon. And after 44 years, no one has come forward to say they were in on it or provide proof of the cover-up. IMHO, these are extraordinary claims and they do require evidence to be even remotely believable.
I agree.
Its not as if NASA suddenly turned up on the moon and said,
"look at us, we're on the moon". That
would be an extraordinary claim, and the HB's would then be right to question it.
What NASA did, was embark on a graduated, step by step process, with testing, analysis, (catastrophic) failure, redesign, restesting, reanalysis, over a nine year period and all in the glare of the public and of agencies both foreign and domestic. It involved hundreds of thousands scientists, engineers and other people. They succeeded and made seven attempts to send men to land on the moon, succeeding on six occasions. The evidence that they really went is overwhelming, if not irrefutable.
The claim that ALL of it was faked, and that not one of those involved in the alleged fakery has come forward to speak about it, is far more extraordinary than the claim they actually went.
I think I read somewhere that it would have been technically far more difficult to fake the Apollo Programme to the extent required to keep it undiscovered for over 40 years, than it was to actually go there. Additionally, it would have been hugely more expensive, with those expenses still ongoing to this day.
