We will now briefly discuss the more controversial pool of cultural information relating to the Pleistocene nonconformity. These are derived from ancient literary sources that reach farthest back into prehistory.
1 There exists extensive tales, worldwide, of an ancient global inundation going back to this era. And yes the natives can tell the difference between a local catastrophic flood and a mega event in which thousands of square miles are permanently destroyed.
2 We have the Atlantis myth that tells of a great seafaring civilization that sinks below the sea in a night. This tale also appears global in distribution. This begs the question of a purely localized event such as Santorini even though there is justification to suppose at least a mixing of the two tales. Good evidence exists for the commingling of the prior global tradition with more recent local events in many of these tales. The global concept does come through as the one safe common element.
3 We hear a unique Indian tale of the earth standing still briefly, and when rotation renewed, the length of the day had changed. There isn’t really enough multiple support for this particular tale, but it is awfully suggestive of perhaps some form of crustal event.
4 It is learned from Sumar, via the bible, the information of between seven to forty days of torrential rainfall.
Other related statements are made, but these are the salient claims. They are also extraordinary and if accepted can only be explained physically in terms of an event that affected the entire globe. Stripped of local observations, we have one claim only and that is that the globe may have received a major environmental shock that impacted around the world and generated extraordinary conditions.
