Answer 1

In reality, Asians discovered the America’s during the ice age. They migrated over from modern day Russia when the oceans were lower and a land bridge was formed. More “modern day” Asian and European cultures took so long because sailing across an ocean is hard. The vikings barely made it when they landed in Canada in 1021.
