Who has seen the Wind?

Earth, Wind, Fire and Water are the quintessential natural forces of nature.
We can see the earth, fire and water but not the Wind.

Who has seen the wind, neither your nor I

Do we have to see it to believe it?

Who Has Seen the Wind?
BY CHRISTINA ROSSETTI

Who has seen the wind?
Neither I nor you:
But when the leaves hang trembling,
The wind is passing through.

Who has seen the wind?
Neither you nor I:
But when the trees bow down their heads,
The wind is passing by.
