"My father was almost entirely absent from my childhood, having been divorced from my mother when I was 2 years old; in any event, although my father had been raised a Muslim, by the time he met my mother he was a confirmed atheist, thinking religion to be so much superstition."

Most famous for being a certain someone’s father, Barack Obama Sr. has only really attracted interest in light of his son’s historic achievement of becoming the first non-white President of the United States. Originally from Kenya, Obama Sr. was born into a Muslim family. By the time he moved to the USA to study economics, it appeared that he had turned away from religion, and had become an avowed atheist. The new President claimed that by the time his parents met, his father saw religion as mere superstition.
