The North American Indians attached no importance to a continuous factual history,and kept none outside of a collection of tribal myths and memories.

This is not strictly true, and sounds a bit self-serving.

But even if true, ya mean, 'Just like us White folks'?? - Pick up the books America Revised and Lies My Teacher Told Me some time;you may get a whole new perspective on "tribal myths" and who uses them for what.
