The belly button, or navel, is a physical feature that typically marks where the umbilical cord connects a baby to its mother during development in the womb. Since Adam was created directly by God and not born from a woman, some people wonder why he would have a belly button at all.
Some interpret this as part of God’s design, suggesting that Adam was created with features familiar and relatable to humanity. It speaks to the mystery of creation and how God chose to form humanity. It reminds us of our unique place in creation—made in His image (Genesis 1:27).
