Why not even consider that the Ancient tribes 5yr old kids were writing on the walls?
In response to, "Why not even consider that the Ancient tribes 5yr old kids were writing on the walls?" First of all, did you mean, "Why not even consider that it could have been that ancient tribes had 5 year old kids writing on the walls?"
Funny how I'm Native but speak better English.
Anyway... it is amazing how fast non-Indian people dismiss anything that Native people knew before Europeans. My grandmother, who was a Sioux woman, when she heard of new scientific findings would often say, "We already knew that." There is so much education that most of you on this post have obviously missed out on... pity and shame on the adult for not "ever even" bothering to find out.
