Riddle: Two archaeologists enter a cave. They stumble upon a man and a woman frozen in ice. One archaeologist says to the other, "That's Adam and Eve." He was correct. How did he know?
Answer: They don't have belly buttons, so they were created and not born.
Riddle Explanation + Meaning
The answer to this riddle relies on a well-known story from the Bible.
Adam and Eve, according to the story, were the first humans created by God and placed in the Garden of Eden.
They were not born in the usual way humans are, but rather were created directly by God.
Because they were not born from a mother, they would not have belly buttons, which are scars left from the umbilical cord that connects a baby to its mother in the womb.
The archaeologist knew they were Adam and Eve because, finding two human beings frozen in ice without belly buttons, it matched the unique characteristic of these biblical figures.
This clever observation within the riddle highlights a creative way to identify these iconic figures based on a detail from their creation story.
Why the answer is no belly buttons
This lateral thinking riddle depends on a detail you are not told directly. The archaeologists see two frozen people, and the question asks how one of them could be sure who they were. You might think about clothes, a garden, or an apple, but none of that is in the riddle. The real clue is in the Bible story in the book of Genesis, where Adam and Eve are made directly rather than born, so in the riddle's logic they would never have had an umbilical cord.
Your belly button is the small scar left where the umbilical cord was attached before birth. So the riddle asks you to connect a religious story with a simple fact of biology. It is tricky because it seems like no answer is possible from looking at a frozen body, until you think about what every other person has. The riddle is a thought puzzle about the story, not a claim about real archaeology, and families can enjoy it whatever their beliefs.
Where this riddle comes from
This riddle's author is unknown, and it has been shared in puzzle books and online for years. It is a lateral thinking puzzle, where you have to use outside knowledge to fill in a hidden fact. Whether Adam and Eve had belly buttons is an old question that painters and writers have argued about for centuries.

How to solve riddles like this
- Ask what fact the riddle expects you to know but does not say. Lateral thinking puzzles often rely on general knowledge.
- Picture the scene in detail and list what you would expect to see. Then look for something that would be missing.
- Count carefully. Family riddles often hide the answer in how relationships overlap.
- Don't settle for "it's impossible." If the riddle says someone was correct, there is a logical reason.
