I watched a documentary on netflix that even if you don't believe the theory about an ancient cataclysmic event around the time of the ice age and pre ice age civilisation it does raise many questions that traditional archeologists and historians have yet to answer. For instance the great flood myth which appears globally in virtually every culture, myths about a great lost civilisation, early human construction which predates the accepted time civilisation is supposed to have started, cities and settlements that sunk when the ice age ended, a lot of these events are confirmed by geologists.
