Actually any day could be the start of the end of the world.... I just did some research and these three events could cause extinction. •A solar flare •A comet or asteroid more than 5km •A super volcano- most likely yellowstone -Solar flares could do some serious damage to our electronics and since we basically survive with the technology these days it might be the end. -A comet or asteroid the size of more than 5km could wipe humanity out. A comet that was 50meters was said to be 1000x stronger than the "Fat Guy". And after the comet hit it doesnt end there, there will be dust covering earth's atmosphere making it impossible for sunlight to enter earth which stops plants from photosynthesizing -super volcano yellowstone 55km wide. Imagine it erupting, will almost completely destroy CA also has the same after effects as a comet/asteroid.
They are all true Though all of these things have something in common. They're all very predictable. So basically we'll know when the last day on Earth is coming..
Cereza had a good point lol. Personally, I don't think artifacts such as the Mayan Calendar spell out death for us, I think it'll be human ignorance more than anything. It's only blissful until we're face to face with Doom's door lol. There's been interesting articles that I've read online, but the one that made more sense than anything was the fact that humanity can destroy itself on its own, no other worldly help
