Laos' mysterious Plain of Jars that has stone jars across the burial ground may be 3,000 years old

New analysis suggests the limestone vessels may be up to 3,300 years old 
But remains found nearby date to just between 700 and 1,200 years ago
That suggests they were used for centuries, possibly by different societies
A body may have only been in a jar until it decomposed and the bones buried
Scientists aren't sure how the urns, which can weigh two tons, were moved miles from where they were quarried
