What beauty has the planet Earth! my gosh!
The only place where life seems to exist;
Discontent man is searching for worlds posh;
In extra-terrestrial planet-list.

The safest place to live is earth as yet;
The only one for man in Solar orb;
Five billion years-old earth alone is wet;
And wears the blue atmosphere as its garb.

The crust of earth solidified from gas;
And animals were born before came man;
The continental drifts, ice came to pass;
But no one knows when human beings ran?

The magnet Earth has gravity of own
Which keeps all things from flying off but down.

Dr John Celes
