The first record of the Riddle of the Sphinx is attributed to Euripides, but probably comes from earlier Greek mythology. It asks, "What goes on four legs in the morning, on two legs at noon, and on three legs in the evening?" The answer is, "A man, who crawls on all fours as a baby, walks on two legs as an adult, and walks with a cane in old age."

A human being. Let me explain: First, when a baby is born, they crawl. Since a human has two legs and two arms, it seems like a baby 'walks' with four legs. Second, during the middle stage of our life, we walk upright, on two legs. Lastly, when we grow old, many people choose to or need to use a cane to walk with, giving the impression of three legs.
