There have been many perfectly valid conspiracy-theories throughout history, such as the princes in the tower and the man in the iron mask, Eustache Dauger, Tony Blair's 45-minute-Iraqi-weapons-of-mass-destruction-threat etc. etc.. However, all such were backed up by vast amounts of anecdotal reports plus endless solid documents etc. When the evidence for a conspiracy theory is wholly underwhelming, contradicts scientific theories, or is heavily debunked with mountains of convincing facts , such as UFOs found on the moon etc., faked Moon Landings etc., then one should not show credence in them. Also, many conspiracy-theories, such as the Illuminati or UFO ones are absurd - I mean, humans/organic beings are fundamentally rather stupid people so the schizophrenic notion that we are all somehow rigidly controlled like in the film "They Live" is not credible. Sure, many humans hold far too much influence over the individual, to the point where many freedoms are denied us compared to Palaeolithic times, but none of these,er, "masters" are superhuman geniuses or whatever.... I suppose it is all to do with the absurd anti-Stirnerite "necessity" of human beings to believe in a higher power, whether for good or ill.
As for the Obama children not looking like their parents.. Well, of course, they don't! Being mixed-race children from 2 mixed-race parents, they naturally would be a wild, random jumble of widely different ethnic characteristics and so would not be likely to resemble their own parents much.
Err, could we get back to the subject of amusing people's humdrum lives instead of worrying about other matters?
