yeag but what type?
Option 1: we brought this on ourselves (probably AI or nuclear)
Option 2: lil green men (aliens decide f**k it we blowing up these homo sapiens guys)
Option 3: spamce (asteroid or other astronomical phenomena)
Option 4: general zombie apocalypse (some kind of pathogen; can merge with other types to become more interesting)
Option 5: The sky will run black with terror And the land will crack with fear. Then, her heart pounding... The EARTH will draw her final breath.
Only then, shining with hope...
Three HEROES appear at WORLDS' edge.
A HUMAN,
A MONSTER,
And a PRINCE FROM THE DARK.
Only they can seal the fountains
And banish the ANGEL'S HEAVEN.
Only then will balance be restored,
And the WORLD saved from destruction. (This is a joke)
