Omphalos is the classical Greek word for "navel." Not coincidentally, the omphalos is also an iconic religious object representing our creation out of chaos--as well as the original name of a modern creationist hypothesis arguing that God created the earth with all the signs of pre-existing age, from geological strata to the belly-button on Adam when God made him from dirt.

Yet pictured above is a genuine miracle: a woman without a belly button. She's evidence of either our imminent posthuman future or a photo-editor getting a bit too enthusiastic with Photoshop's clone tool.
