Jenn, the Bible tells us in Matthew 24:36:that, "No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father." So people can speculate all they want. It could be any day or a hundred, a thousand or more years from now.
If you die in the next 2 weeks, it will end pretty soon for you. The rest of us will keep enjoying it. The world was supposed to end about 300 times already, so I wouldn't place any bets. Also 97% of all species that ever existed are extinct. We have been here only 3-4 million years. Compared to 300 million for the dinosaurs and about 2 billion for our planet. Our demise would be as significant as the extinction of the dodo bird and the passenger pigeon. So I wouldn't worry about, it is not as if you had any say in it.
