Both limited knowledge about the older Precolumbian cultures and recent discoveries, such as jungle-reclaimed Maya cities, allow many theories about alien links. Olmec statues in Colombia would portray inspiring or manipulating extraterrestrial visitors, iconographic and other intercontinental parallels, such as a cobra-like sacred snake or lingam-like monoliths are attributed not to migration or coincidence but rather an alien disperser, especially the assume Cham diaspora from a Vietnam home country. The means would include alien technology, notably for flying, which would power the strange contraptions from Hindu mythology. Scarse evidence from Conquista days would be either destroyed on Catholic Church orders or hidden in the Vatican secret archives.
