Are aliens coming in 2012

Answer 1

there is no evidence of it, the only thing signaling it is the end of a calendar that could mean anything from the Mayans getting bored after five cycles or believing that five cycles heralding the serpent coming down the side of their temple stopped them from needing a calendar carved any further, to them starting to use perishable materials for writing their calendar. The best way I have heard it described is, our calendar ends every year, doesn't mean the world is ending, just that its time to get a new calendar, and the Mayans were probably simply obsessed with astronomy like many other ancient cultures.
