his sister says Obama was born at one of two hospitals in Hawaii(I forget the names)

One sibling said one hospital; another said another hospital. Neither of them could possibly have been eyewitnesses. His grandmother, though, and older half-brother and half-sister, who all were old enough to remember his birth, claimed to have been present at his birth in Kenya.

You can go to Kenya with a 20 dollar bill and get a dozen people to say anything you want them to say.  Great evidence!
