Either the world ended on December 12, 2012 or it continues today. The world did not end of December 12, 2012 so, the world continues today. * Is this an explanation or an argument

Explanation: It is not an argument because it is a fact, and it's not something you can argue, or debate about. The world did not end in 2012, and that is an absolute fact; no matter how hard you try, you can't make an opposing claim or argument because it will be false.
