about the moon landing:
how do you personally know we went?
what evidence do you have that proves it?
the reflector that is mentioned could have been left by an unmanned craft.
How do I personally know?
Well I could say I watched it on TV, or that I read about it, but that obviously is not going to satisfy any nutty conspiracy theorist, is it?
Or I could mention the loads of unique Moon rock that the Astronauts brought back, but again, that wouldn't satisfy any of our nutty friends either, would it?
Or I could reference the actual photos taken from lunar orbiting probes of the LM's on the Lunar surface, and the tracks of the Lunar buggies, but even that isn't going to convince any real dyed in the wool nutty conspiracy theorist.
Let's just say that anyone who believes that the 6 Moon landings, plus the failed Apollo 13 and 8, 9, and 10 Moon trips, were somehow staged, with the whole world watching them, including the USSR during the period of the cold war, should really be certified officially insane.
Let's just say that anyone who believes that the literally thousands of people that were involved in such a project, including those at Parkes Australia, who had the job of relaying communication between the Apollo craft and Houston, could all be trusted to keep this supposed staged event secret, let's just say that anyone who believes that, should also be officially certified as insane.
Not sure if that answers your questions but its the best I can do.
