By 4000 years ago the Americas were pretty much already populated, a dribble of a few thousand people from china wouldn't have mattered at all. There is no evidence of a continuous migration over the entire 12 to 16 thousand year period. As for the cities of the Native Americans they pretty much disappeared when disease was introduced by the Spaniards. The entire culture of the Mississippi River was completely gone by the time the anyone else tried to explore that area. Only deserted sites and moldering ruins were found a hundred years later. You need to get your time frames in sync, 500 years ago and 4000 years ago is not a comparable time period. It would be like comparing the revolutionary war to ancient Egypt and trying to say the fall of Egypt was responsible for the revolutionary war in North America.
