He was in Indonesia until 1970 or 1971, depending on what article you read.
He was also shown in a dated photograph with a classmate named Scott Inoue in Hawaii in 1969.
That gave rise to the tongue in cheek statement 'there must have been two of them!'
And then it was discovered that Opiyo in swahili means 'first born of twins' -
And no one can find where and when 'David' actually was born or when he died...the fact that zero resembles 'David' gave rise to the legend.
Helped along of course, by 'Dreams' in which zero describes an incident in the streets of Nairobi, where someone mistakes him for 'David' - because he looks so much like him.
And that's all there is to it. Mark maintains he is YOUNGER than zero...but the child who resembles the little 'Zero', is YOUNGER than Mark...by perhaps one year.
And little zero/David doesn't look as if he could have had the same parents!
So someone is lying, but that's nothing new.
the image is from Mark's own website, he has identified the two litle boys as himself and 'David'
PS. One very good reason for Mark to insist he is younger than his 'half-brother' obama just might be - he may have been born on the mainland US before his father showed up in Hawaii in June, 1959. Now wouldn't THAT make in interesting story? The 'old man' had plenty of time, remember? He hadn't been back to Kenya FOR SEVEN YEARS!
