A Riddle

I am older than the sea.

You hardly see me but I can bury you alive.

I can destroy everything you build. I defeat water and air.

Some will never touch me.

Others, I am inside their most treasured memories.

I have held lovers in my arms;

I have stripped flesh from bones;

I have erased all trace of you anywhere.

I have listened to you question the meaning of your life.

I have caressed your babies’ feet. They delight in me.

I have been sold across the world.

I have been cursed for being places I shouldn’t.

I am everywhere.

I am easily forgotten.

I am not given enough credit.

What am I?
