Can anyone please kind of debunk this one for me? I have a friend who is absolutly convinced that the Mayans predicted this in 2012, and shes gone so far as to start building an underground shelter of some sort for it. I cant seem to convince her that this is utter nonsense, but she believes it because she belives anything with the title "ancient prophesy" and what not..sorry the post is somewhat confusing im very tired heh...Thank you in advance
