This photo looks to be retouched (imho).
I don’t think it’s a coincidence that the darkened areas seem to form a pattern (looks like a guy on a motorcycle to me). They were darkened specificly to make them jump out and form an impression.
If you step back and look at the entire picture, you can see several “images” (there is at least one clear human head, as well as a large hand).
As someome pointed out, there patterns are the result of what has been a common farming technique in the area for centuries.
IMHO, this is no different that looking at clouds. Look up at the clouds, and you’ll see all kinds of images Some people used to think this was proof that God existed, because he put images in the clouds. The truth is it is the result of coincidence and human imagination.
Look at any google shot of neighborhood streets, and you’ll have the same effect. You’ll see images in the street patterns.
Humans look for patterns in everything. These patterns in the farming rows are just due to human imagination, nothing more.
Quick joke. Guy goes to a therapist and the therapist starts the session with an ink blot test. 1st picture the guy identifies as a man and a woman making love. 2nd as two guys making love and 3rd as two women.
Therapist: Good God, man, you are obsessed with sex!
Patient: Me?? You are the one drawing the dirty pictures!
I know several other archaeologists working in these regions in SA right now that that are working on sites even bigger than this site. Wait until you see the things that they’ve found that haven’t been published yet. You won’t believe what’s coming out in the next few years...trust me...
