Why do you have fingerprints?
We have fingerprints because it provides a grip. If your finger tips were smooth it would be harder to grip things. The exact pattern is unique to each individual, although there are standard configurations.

What causes us to produce fingerprints on a glass?
Fingerprints are left on glass surfaces due to the natural oils and sweat present on our skin. When we touch glass, these oils and sweat transfer onto the surface, creating a visible fingerprint pattern.
