I am an EXPERT on countries

Beneath the sky so vast and blue,
Lies Earth, our home, both old and new.
With mountains high and oceans deep,
A world of wonders, secrets to keep.
Forests green and deserts wide,
Rivers flow, and tides abide.
From polar ice to tropic sun,
Earth's beauty shines on everyone.
A planet teeming with life and grace,
In every corner, every place.
Let's cherish, protect, and understand,
The precious gift of this wondrous land.
