Forethought furnished me to men;
For ages I sourced all.
But slowly, as the men advanced,
I watched my kingdom fall.
I used to give so much to men,
But now they need me less.
Perfunctory my uses now;
Allure I once possessed
Replaced, am I, by lightning caught;
May Franklin be most cursed.
He gave mankind alternatives,
And so my growth reversed.
I gave to men their healthy meat;
I made them safe at night.
I gave them weapons, traps, and shields;
I shared with them my might!
But still I'm used, albeit less;
They see me oft as "quaint".
Where once I was in every home,
Now usually I ain't.
They think me fine on wintry nights,
But keep me in my place.
They build me traps of steel and stone,
And to their friends showcase.
"Oh, look," they say, "we tamed the beast!"
I roar internally!
"That's very nice," their friends reply.
I spit my tongues at thee!
Let me loose, I shall destroy
Each thing that you hold dear.
I rage against my captors now;
They're always right to fear.
I'm ancient and I'm primal too;
I date from long before
The rise of all these puny men;
I wage a ceaseless war.
All that you built upon my back
Shall be destroyed by rage.
I'm wild, devouring all I see;
I grow, but do not age.
You may send troops with special suits,
Who try to beat me back,
But I return and start again;
With lightning I attack.
So sit or stand, you fleshy thing;
Believe that I am tamed.
My will be told: the world would be
Who am I?
Explain as many clues as you think necessary to show how clever you are / how obvious I am.
