Why Do We Use ‘Fingerprints’ to Identify People?

Fingerprints are like a special code on your fingers that no one else has. When you touch something, it leaves behind this code, and scientists can use it to find out who touched it. It's kind of like how each person has their own unique shape or voice, fingerprints help people tell apart one person from another, just by looking at the tiny patterns on their fingers.

Every person is born with different fingerprint patterns because of the way their skin folds and grows while they're in the womb. Even twins have slightly different fingerprints. That’s why scientists use them to identify people, no two fingerprints are exactly alike.
