there are other bases for this theory other than the mayan calendar.
ancient china had a book they used for predictions, had to do with series of lines that translated out to words through some system. dont remember the name of the book. they predicted a terrible event in 2012 around dec. if not dec. 21.
ya merlin.... the actual dude, also predicted this. was myrddin his actual name, i know it wasnt merlin.
nastrodamus coulda just been playin off these.
there are a few others who predicted that 2012 would have a major event. some were civilizations that never met in any form.
i saw this on the history channel... they had a 2012 special. i found it interesting. personally i believe something will happen 2012. of course nothing of absolute destruction. something more along the lines of an astrological shift, like a new alignment in the system. nothing that will effect the world too much, maybe a lil.
either way it doesnt matter to me. if we die if we dont die.
