Why do you have eyebrow?

Answer 1

Eyebrows play a very important role in keeping moisture out of our eyes.

Just like an umbrella keeps our bodies dry from the rain, our hairy eyebrows keep our eyes dry from rain or sweat.

When it's pouring rain outside or when sweat drips down from our foreheads, our eyebrows divert the flow of water or sweat away from our eyes.

By catching the water or sweat, our eyebrows not only allow us to see more clearly, but also keep salty sweat from burning or irritating our eyes.

Answer 2

Humans have eyebrows to show facial exspression
