Dont forget the Ice Age of 10,000 years ago that produced thick glaciers over much of North America that both came and WENT; on its own with no help from huminoids,,,unless they produced zillions of campfires emitting billions and billions of tons of greenhut gasses back then.... Proving the earth/sun can fluctuate temperatures to a great degree on its own volition.

Try Hapgood or Velikovsky for interesting ice age thories...
