Yeah I think that's by far the most compelling argument - Derek from down the road with his toy telescope can write a website and tell us all about how the shadows don't do this, and the flag flaps in the wind, so it can't possibly be true. The Russians though, even with some of the best technology of the day didn't notice that people hadn't actually landed on the moon.
There are conspiracy theories about the moon landings, about 9/11, about global warming, about WWII Nazi sympathisers in the USA and Britain, about the holocaust... the point is not so much whether any of them hold any water, but just that people like conspiracy theories - there's one about pretty much anything, and I think it's the direct result of people wanting to feel like they know something other people don't, that ability to stand up and say "everybody's wrong, and I know the real truth", and then they look for evidence. I'm not applying this to the people in this thread who express doubt, that's different, but people clearly want to believe an alternative truth and hence they find what they need to prove that alternative.
Oh yeah, just one thing - I don't understand your comment about reflectors on satellites Zak, are you suggesting that it could just have been crash landed onto the moon and didn't require any human intervention?
