Drawing a realistic(ish) person without a bellybutton, would be just plain weird, though. I can hardly imagine a person without a bellybutton. The artist probably even less so.

It's art.

Religious paintings are rarely, if ever, meant to portray a literally true picture.

Michelangelo made a painting of God and Adam touching at the fingertips on the roof of the Sistene Chapel in 1511. It is art; representative of meaning but not literal. It has always been obvious that God is not or should not be a physical being in His totality.
Just as a picture of Adam and Eve in Eden represents the beginning of man, so to does Michelangelo's picture symbolize the connection between man and God.

Could be that God just put belly buttons on them. I mean, It's God. It can probably do that pretty easily.
