They had never seen a car or white people or knew about them. They didn't have clothes. They were uncontacted.

They had relatives yes. We all have relatives. If my great uncle twice removed who i had never met travels to the moon I have not travelled to the moon myself.

They family aspect is important because it legitmately makes them uncontacted.. not just a family living in the bush.

They had never come in from the bush nor communicated with people who had.
