A story about a story by Duane Michals

When I saw these pictures in a website, I was very amazed how genius the artist is. It is like we don’t know which picture is first.
Firstly when we see the pictures, our brain automatically follows order by order but the last picture was shown, every body are confused about picture because we can not organize which is the first.
I thought Maybe the first can not exist in the world because everything are going around and around. Just human can not identify this truth.
