Modern meteorologists can barely predict the weather, with all of our advanced technology at their disposal. NASA can barely get a shuttle launch off without a hitch anymore, and it takes them years to discover new planets and star systems. Plus, without those modern advancements, we'd be so outclassed its a bit embarrassing. Mayan astrologists/meteorologists, could identify celestial bodies and predict astrological events thousands of years in the future with nothing more than charts, their calander, and the crude wooden shafts with yarn attached, used to line up the stars in the sky. And they were accurate to the very day.
