You think you're from Sky World, tell me all about it then.
The Sky World is a land high above the Earth, where life was much like it was here. The Sky Woman was the first human on Earth, when she fell. She landed upon the back of a Turtle, and various sea creatures provided her with land by scooping mud from the bottom of the sea - this was "Turtle Island", which we now refer to as "North America".
We have always been here, and we shall always remain here.
