Who Am I?

I am the mountain 
I am the plain
I am wind
I am rain
I am the planting
And I am the grain
Who am I?

I am the river
I am the sea
I am you 
You are me
I am the _ (grass? flower?)
And I am the tree
Who am I?
Who am I?

I am the sun, the moon, the stars,
The planets, Jupiter and Mars
I am the north, south, east and west
Do you know who I am?
Have you guessed?

I am the winter
I am the spring
A summer flower opening
Autumn leaves
A bird on the wing
Who am I?
Who am I?

I am the children
Every boy and girl
Do you know who I am?
Can you tell?
I am the WORLD!
