The end of the world? I think the world will be around for a long long time The end of life on Earth? Natural causes The end of humanity? Humans
The worlds going to be around till it get's enveloped by the sun in a few billion years. As for people, we'll end up genetically modifying life that will out evolve us, and we'll eventually just breed into them... sapiens will become extinct, and a new species will rule the planet.
When you think about it, it is... Theres no reason to be scared of evolution... its nature at its most beautiful.
One of these days, just for no reason, every living creature on earth will lose the ability to produce life, and everything will eventually die out.
did you ever think, that maybe the world already ended. and we are all in hell righht now, and never realizing that we're already dead.
