Right now it's our turn, and when the Earth has had enough pollution, BAM. Some stuff is gonna go down like in movies such as The Day After Tomorrow and 2012, and then just like that, we're gone. Then, some CRAZY shit goes down on Earth. It's changing, moving, and resetting itself. Then, we start all over again. This sounds like it makes sense, right? We start, we progress, the Earth can't take it, it resets, and we start all over. I wonder what turn we're on now...
