Nothing is forever. It's a grim reality but no matter how hard we try and ignore it, our inevitable demise looms ahead on the horizon.
And while we individually have our unknown expiration dates, the fate of the human race is an unfathomable mystery that will continue to elude us.
Hopefully, the fateful event is thousands of years beyond our lifetime.
Curious to hear people's predictions, Redditor Nuggl3s7 asked:
"What will be the reason for human extinction?"
Redditors had their sci-fi theories.
Remember Pixar's WALL-E?
"Im gonna have to go with the WALL-E theory that we will turn our planet into a giant waste basket."
– SheriNormand
We Are Not Alone
"Something from space probably, there is some scary stuff in the void."
- Mylastbreathgoing
An AI Revolution
"We merge with AI end become a different species, thus ending homo sapiens."
– Soggy-Impact-5852
It might take one huge impact.
We Would Never See This Coming
"Either a massive space object colliding with Earth, or Mother Nature finally gets tired of our sh*t and concocts a virus 10 times more contagious than COVID and several times more fatal than Ebola."
– POL4Life
A Big Bang Theory
"A Coca-Cola truck hits a Mentos truck."
– No_Finger9730
Ouch
"Every human simultaneously stubs their toe at the same time. R.I.P."
– LeakingLantern
Some speculate the big disaster will be one of our own making.
Self-Destruction
"Generous of you to assume it will be error. Right now there's a large percentage of the decision makers in the world operating by 'This will have catastrophic effects if everyone does it, but it will be profitable if I do it. So everyone else needs to stop, but I'm not going to, and also I'll be dead by the time the really bad consequences happen so f'k all y'all I guess.'"
– ProjectGO
Corruption
"For realz tho…no big catastrophe….just a slow drip of f'k you gimme your money while I ruin the world and whattya gonna do about it brah? Nothing, that’s what. If you can’t stop me I’m gonna do it indefinitely. Big fish eat the little fish. Then eventually no little fish left and big fish go bye bye 👋"

There's A Sad Pattern
"Considering how poorly humanity as a whole dealt with this time's pandemic, and how much we overestimated their intelligence, yeah. 5 centuries is a generous amount of time, I give it 3 centuries."
– ToastWithNaomi
Mea Culpa
"This, I think it will be our fault and only our fault."
– RandellX
Growing Lack Of Intelligence
"Gross stupidity. In less than 500 years max."
– Centretek
Many Redditors speculated our own shortcomings would inevitably be the end of us instead of a meteor shower or a hostile takeover of extra-terrestrials.
Interesting.
It says a lot about our lack of humanity, doncha think?
