In this episode we begin by discussing the recent developments in Mexico and Guatemala, where evidence of ruins of enormous urban areas have been discovered associated with known sites. Basically, nerds showed up with helicopters and lasers and demonstrated how to do archaeology in the 21st century. We also discuss a fascinating submerged cave system in Mexico that has been underwater since the end of the ice age, which was found to contain bones of pliestocene animals, human bones and artifacts, wall carvings and stone staircases and altars. Of course the constructions are attributed to the Mayans who were in this area around 900AD, which is a tad late considering the cave has been submerged for the past 10k years or so. We talk about the odd association with gods and turtles in mythology all over the world, and how there is evidence suggesting these turtles actually represent some sort of mechanical vehicle piloted by a member of an advanced civilization(alien or not), and whether these vehicles could have been utilizing some form of mercury vortex engine, as is implied by the myths  Brothers of the Serpent Episode #036
