12/21/12:Is It The End?

this will happen before the end.

Everyone is saying the end of the world is going to take place on Dec.21.12. I dont believe this will happen first off the bible says no man knows when the world will end. or something like that. People who believe this is RETARDED! ON MOMMY! They say the Mayans calendar end on this day and it complete some cycle of the earth and every thing will start all over and bull. I believed this would happen till I googled it and went on the NASA website.*I will believe NASA before the history channel* here is an link if you would like to look into this bullsh*t      http://www.nasa.gov/topics/earth/features/2012.html
