NASA does not know of any statements by Sir Arthur C. Clarke that suggest "... pretty convincing proof of the existence of large forms of like on Mars,"
Yeah, right!
NASA named the daggumed NEW MISSION to Mars, "Odyssey". ___ in tribute to Sir Arthur C. Clarke's, "2001 - A Space Odyssey".
So basically what you're saying is that because NASA named one of it's probes after Clarke they know everything he has said? This comment was made to Space.com, a great site, but not exactly a major headline news organization. I have been unable to find the remark reprinted anywhere else except on UFO-type sites.
Here's the link for those of you curious:

Consider NASA's motivation, what would it have to gain by deliberately lying to FACETS on this point? That's right, absolutely nothing- in fact, it makes them look stupid, so why would they do it purposely?
For those of you who still believe this is all a big conspiracy, please consider Clarke's closing words at the end of this article:

And then Clarke took an opportunity to rebut those who refuse to believe even well documented events, specifically, the Apollo moon missions. Responding to a recent television program claiming the Apollo landings were faked, Clarke said, "I can't imagine anybody being stupid enough to think that a program involving hundreds of thousands of people, carried out over a period of [more than a decade], in a blaze of publicity, could possibly be faked. Ben Franklin said, 'A conspiracy of three people can be kept secret, if two of them are dead!'"

It is quite clear that Clarke does not believe a conspiracy to hide something like intelligent life on Mars is feasible.
I am quite open to the possibility of life on Mars (although I think there is a lack of evidence for intelligent life), but I am firmly with Clarke on this one- a conspiracy to keep real evidence of this from the public would be virtually impossible.
