Wonderful post. I've done a lot of thought in this area myself. Its hard to actually know what they were representing, but damn if it isn't "controversial."
Thank you for taking the time to clearly present this article in a format that is easily digested by the reader! Great information to have floating through our community! :D
Thank you so much, I tried to do my best (as always).
Also, I tried to use some official sources.
When I was in Arizona I got the opportunity to head out onto some ravines out in the middle of nowhere bordering several reservations. There were petroglyphs on the walls that were incredible. They told stories of otherworldly creatures visiting. There were clearly images of man and woman doing their daily activities, but then there were ones that just could not be explained easily and had very humanoid figures to them. Always had a very odd feeling in that ravine.
It would be great to go there and make an original steemit post, unfortunately I'm in Europe :)
