Are you scared about the world ending?

I do not believe any of that. Yes, the Aztecs did predict some historic events that actually happened, but they also predictd that the world would end at the begining of the second Milenium(Year 2000). Now, because they were incorrect, they decide to change the date. Also scientists who actually have some proof, not just predictions, that the earth will not be hit by anything nor will it explode on any datee for roughly 5 billion years. And WWIII will happen i think, but not for a while, and it will be a fight for water, meaning we are running out of our Earth's fresh water supply and they will be a war over it.
