the moon landing must be real, other countries also explore space, i doubt they would lie also.
but i think that the government hides things from the public to protect us. for instance, if the whole roswell thing is true(whether it is or not, lets not get into it), but say that it was, and the government told the public that an alien crash landed on earth, i would bet that the public would freak out. remember "Y2K", that scared the crap out of a lot of people(i just hoped my HD wouldn\'t crash), but imagine an "alien" on earth. whatever, just my opinion.
