i remember the face on mars fiasco. when nasa came out with improved pictures showing it just to be a natural rock formation, the story changed into it all being a nasa cover-up. I don't like cover ups and conspiracies, or accusations of them, either.

i'm sure cover ups and conspiracies do exist in the real world, but when they are used as an excuse for a failure of the facts to fit the theory, they had better be real convincing. its just too convenient to blame some secret evil society every time you get caught with your hand in the cookie jar. it sounds too much like "the dog ate my homework". maybe its true, but its been used one time too many.
