You obviously haven't read the latest literature on cloning. To date, primate cloning has not been possible.
Also, reincarnation, by the mythological definition wouldn't involve dna or the remains of the individual.

Governments keeps secrets. This is a fact of history. Our nation's enemies are different, but they certainly exist. National security is still vital. Just because the area is off-limits, doesn't mean that there is some information there that the general public would benifit from knowing. Disclosing the "need" for the secrecy might, in itself, reveal too much about national security.
As far as keeping the information from senators and representatives, they are temporary and fallible. If they don't have a need to know their knowledge should be minimal. As to those who have suffered from radiation exposure.... well... life ain't fair, but the greater good of the nation should take precedent.
People lie. Get used to it. It's a human condition. Sometimes a lie is necessary for the greater good. Most times I am opposed to the far right ideaologies of administrations like the current one and I'll add my vote against them in 2004, but the secrets should be maintained.
Simply not knowing what they are, doesn't mean there's some conspiracy against the American people. It certainly doesn't mean that there are aliens and alien technology stored or explored there. Though I'm sure that the powers that be are happy to let that myth/urban legend perpetuate... it deflects the attention from the real issues.
Also, since we don't know what the secrecy is about, how can you assume that we shouldn't know. I concede that there is a possibility, hell, even a significant probability -based on past government behavior, that the information at Area 51 could be detrimental to the public. But the probability is still low enough to be tolerated.
