An interesting book about Mayans Ive read recently put a twist on the structure of the temples ,most are built higher than any of the highest ground in the surrounding area,this gave thought to how these were more like bunkers than temples.Then ties possible events in their calender to a reoccuring celestial event ,mentioning meteor impacts ,all which if witnessed by them would be an all life changing event.The newly found conjioned evidence how the impact zone that ended life for the dinosaurs is in this same region ,then compels the thought that this related earth debree may be revisiting an earth ordit on cue.Splice this all together seems odd, but science and fiction sometime comes out plausible.
