Will the world be ending soon?

I know this is sort of a really stupid question, but like it seems like it is, everyone is saying it is. And there isis even a big billboard around where i live saying " God's extermination May 21st." And it says a bible verse on the bottom. Also, we had the Oil spill, it killed so many secreate rsres, Japan, which killed so many people, and radiation made it so we can't ever live there again, Then earthquaketornado'sdos killing people, and ruining all of there homes. Texas fire outlining the whole outline of texas burning tons of the land their and ruining homes. Even tornado's here in pennsylvania killed some people.
