Cataclysmic Gigaton

Total bombardment
Cataclysmic gigaton
Twisted screams of billions
To be heard by no one
Deluge
By fire
Humans final mistake
Catastrophic death
In ruinous
Quake
Ashes of vaporized cities
Sit on corrosive earth
In acrid fog
Stench of burning death
Woven into noxious smog
Mutually assured destruction
Only the buzzing croak
Of this smoldered landscape
Will echo until
The end of time
