The progress of old world civilizations vs new world civilization

by UnbarringTomb

Ive been inquisitive lately as to why civilizations of the new world [the Americas] haven't advanced as much as the old world [Europe,Asia,Meso,Africa] before there discovery/arrival in terms of technology,culture,science since humans did have a presence for about 12k+ years in both continents?
