Answer:
i Say 20% ,
The Mayan Calendar Point ended December,21,2012 , This Can also mean For a Arrival of Something,You Dont Know..Or End OF World Or time / This May Happen or May not Happen * Many chances It wont happen , For example Year 2000, Said Earth Will End it didnt , Years ago was the same thing, And it didnt happen.
i Think its a Type of Myth Or something like that/ Tho in The bible Jesus did say
''Earth Can End Soon''(Something Like that)
Peoples say Sun Connects with All planets , And Milky Way , Which Makes a black hole and can Damage us.. (Either fake Or Real) No one Knows/(So the Sun and Earth lined up perfectly along the Milky Way)
But For earth to end Should Take a Long time.... * but inCase.. it Really happens
Celebrate With Friends,Family,Neighbors And Everyone you know/ For Your Last time together... Be Prepared For anything :D
