Conspiracy theorists; don`t you just love`em?......their intricately deluded constructed versions are always so much more complex and impractical than any (so-much simpler) reality. 
I wonder if in Jesus` time if there was a conspiracy-theorist saying that the Crucifixion was all a Jewish plot to discredit the Romans. 
'The people`s popular front': pah!...`splitters!!!!! 
I am sure that did and has continued to happen, especially as Pontius Pilate was very unhappy about crucifying Jesus and going along with the demands of the Jews

.
With the moon landing, in addition to what I have already stated, it must not be forgotten Debs that Apollo 11 was followed by the landings of Apollo's 12 - 17 (ex 13 of course!), so are the conspiracists really saying that all these could be a delusion, set in some warehouse, when the Russians and the World are watching, with specimens being brought back with fully filmed module landings in the oceans??
Sorry, but the facts do not back them at all, and yes Debs as long as there is human beings and events transpiring, then conspiracies will be concocted!!
